Hello fellow gays of Reddit - I've been a huge fan, and an even bigger lurker on this subreddit.
I come humbly here to ask your opinion on a matter that is making me, and my close friends, crazy.

TLDR: There is a PT in my gym who keeps flirting and accepting my flirts, yet he has a GF he never mentioned to me, that i discovered only after he gave me his IG. He also has a gay voice he uses only to greet me which is sus.

The Prelude

I am, of course, a gay man. Not just a simple Noth American homosexual™, but an italian beefcake living his rainbow life in an italian metropolis in the norhem part on the peninsula. This context is important, as queer lingo and culture is not widespread here, and certain words or slang is not known to women or heteros. Forshadowing.

I recently decided that a weight loss was due to this handsome tall, and modest hairy gay man (sorry gay bear lovers, another lost to the gym culture), and along with a meal plan I joined a local gym. All fine and dandy: I lost a bunch of weight - a lot of it, close to 30kg in 7 months, I SWEAR NO OXEMPIC JUST SHEER DESIRE TO DROOL AT SOME HUNKS - and build a nice jawline that envys the stinkiest of the alpha men on Tik Tok. My sharp jaw could face any american imperialist CEO to their unfurtunate demise. I'm not effeminate in any way, although I do "sound gay" - you know what I mean, it's not just a soft voice, it's the added dick desire flavour that makes "the gay voice", gay - and I wear a rainbow band on my apple watch. Although I say to my homophobic mom that it's the peace flag, it's unmistakably a gay band.

A smile, two smiles, too many smiles

Later this summer around september, a new personal trainer (cliché, don't you dare judge) appears. I always been happy to talk to anyone, as I enjoy the gym enviroment quite a bit. I am amicable to the other PT over the gym, but this one sounded alarms. After a couple of weeks of his orientation he stated to smile at me in a way no other hetero dared. A full sincire smile, with some hint of lust. Initially I simply ignored (and gasped, as he's way too hot to be going smiling at people like that) as a token of friendly professionalism, but he continued. He started winking at me and staring, and I started noticing he didn't smile that enthusiastically to anyone, but me and other hotties (usually women). And then I started wondering: "Is he gay? Like thank you for boasting my ego, it's a service I didn't pay in my gym membership but quite appreciated". Day after day he smiled and said greeted, he noticed my gay glances™ at him, and he looked back smiling saying "Hey, everything cool". But I'm not delusional, he could just be friendly, so I just kept glancing and occasionally fantasizing.

Smiling, now 100% more flirt!

He started to talk to me, asking how I was, what I was about to do in the gym, and he started to initiate small talk. I never initiate a conversation as I'm shy like that, but if you do I become the rizzler and super extroverted. I have to be honest, initially I was too shy to even respond to his small talk I very much shrugged him off like an annoyance (he initially was one, if I don't find you on sniffies or grinder ya don't have the gay), but he persisted. We started to talk a bit every day, to the point that he started to follow me in the gym and find me to talk if I didn't talk to him first. But still I said: "No spicyclichè, unless you have proof he's just a silly little hot hunk of a men. He doesn't want you or love you."
But here three things that happened: 1. I wore a tank top while I was doing a shoulder exercise and my armpits were on full display. Non only he looked at them and smiled and rose his eyebrows and said hey (sus). 2. I changed my look after I was gone for two weeks and after I returned to looked to me twice stunned with a awed looked (raise eyebrow mouth open and everything). 3. Another day I was returning from the gym bathroom with my hands still wet from when I washed them, He wanted to to a bro handshake but I warned him they are wet, joking they might wet from piss. You know what he said? "I don't mind it, it depends which side you are on" and I said "All the sides everyside possible" (being from the other side means you are gay in italian lingo). He smiled and still grab my wet gay hands. GAY.

WTF is happening there?

He kept coming and talking, and only after then I started wondering. One time he asked what I was doing this weekend, and I jokenly said "Having a little fun with the alternative sides (like having a gay fun)" He looked at me a bit more serious inclined his head squinted his eyes and sayd "It's good to have fun, but be careful". Jealousy my gay friends, that face was pure jealousy. I came back the other week and I said to him that I ended up having a chill work fueled weekend instead, and he smiled and commented that I did good. This is sus. But this isn't the only time he was a bit jealous about other men talking to me. At one point he said to me "damn I have to work this weekends, do you you come in the weekends?" I said "Yes, ofc how can you work without me smiling at you (look at me, flirting with gay)?" he replied "Morning or the afternoon? and I "Morning maybe". He said disgruntled "Awe, I work only in the afternoon" and I replied "Lets see then. It depends how energetic I wake up, see ya tomorrow". The next day, ofc my gay ass was there in the afternoon ready to see his reaction. He not only shouted HEY!! YOU CAME but the came rapidely at me with a hugging desire. Gay friends, you don't hug a custumer or an acquaintance you just met a month ago, especially if he is gay and he is flirting. Us nothern italian don't hug, it takes time and a reasonable reletionship. He is also a bro type afraid of judgement so it's not in his character (forshadowing). From that day he always greets me with a hug, the only time when he doesn't it's in front other PTs. He started confiding to me his insicurities (I have to say again, I know him for two months) his job hassles and how some other PT don't see him as equal (he's an outsider that become a manager, so other PT started to gossip and sabotage, poor thang). He started to come close to me even when I am talking to other men in the gym while looking at me. GAY. He commented jokenly that I shave my beard wrong and after I said "I'll cut it off then and I'll become a twink" he started laughting. Gays of reddit. Twink isn't a meme in italy, it's not a term used by heteros whether they are women or men. It's so LGBTQIA coded here in italy that it surprized me he knew. he always asks about things I say bc he con't understand them, so laughting at twink without asking what's a twink is sus.

IG and I became crazy

Today I listened my friends and I asked his IG. He gave it to me immediately, not just his workout profile but his personal one. Ofc, He's hotter shirtless. HE STILL DIDN'T FOLLOW ME JET (if he doens't I WILL MAKE SURE TO MAKE HIM NOTICE MY ANGER) He followed me, I'm happy. I commented something that his bio is "Grab the opportunities least expected", saying "Oh like me asking your IG". After he smiled we continued talking. I looked at his IG: could be gay or hetero. Except a carousel of him on vacation with a last pic with his GF. God wants me to suffer. He doesn't have any other pics with her, she also has a single pic and it's with him. And yes, it's recent. Why didn't he mention him having a girl. He's a nerd of southamerican culture and he always talks about how he wants to know latino culture more and how he's fascinated with my heritage (I'm half brazilian, so he was so intrigued). YET, he never mentioned his GF who is latina. The opportunity arose, yet he didn't mention her. Weird. He did comment on how beatiful some of the girl were on the gym while looking at me. Never his GF. This is the part that is making me crazy: He may be Bisexual, because if you were straight he would not be so interested in me after all my obvious flirts. It's difficult to be bisex especially if you live in the rural part of the most right wing part of italy like he does (he commutes to the city). It's weird in all the sense that is weird.

Conclusion

What do I do? Ofc I will keep flirting. I can't ask him out as it's not the time to do it, especially in his position and I don't have time to date this year, maybe next. It's confusing. Help.

Ps. If you visit my profile, you'll se old pics so don't thirst.
