I'm 27 and shes 22, together for 1y 3months Last friday I went to visit her early in the morning (10ish) and for my suprise see a car in her parking spot (she doesn't own a car or drivers license). Ringed the doorbell and she looks through the blindfolds and starts texting me how i'm the evil guy that i woke her up, and doesn't let me in, i just mention that nice car in your parkingspot. her answer to this ''it's the neighbours sons car since the guest spot was taken''. I just said ''if you have nothing to hide let me in and prove me wrong '' her: ''I dont have to prove you anything''

next day (saturday) and again on saturday the car was still there when i went to check at around 23:00

sunday i said i want to talk in person about what has happened so we went to store together, then to her place. i bring up the elephant in the room and tell her me: ''if he's just a friend why didn't you let me know you have friend over'' and ''why not introduce me to him? am i that bad boyfriend material that i cannot be shown to your friends? or did you not tell him that you are in a relationship?''

her: Not if you come unannounced to my door and start harassing us (all i did was knock on her door because my mental health has been fucking shit and i was asking for a hug)....

me: again if he's just a friend why not let me know he is over here?

her: (aggressively) i dont have to tell you what i do on my free time

me: well you don't but i tell you what i do and who i meet, i expect the same courtesy from you.

(btw good to know at this point) for last 3months or so, i have driven here where ever when ever she has wanted, i have washed her clothes, sheets, anything that can be put in a washing machine really, i have cooked for her, cleaned, done her dishes, bought food, bought an air fryer, and countless things, all i asked for was closeness, which i received very very little.

she proceeds to lie about him that his ''friends'' cars steering was brutally broken so he needed to leave the car at her parking spot on thursday, had coffee and left

i know now that she lied because yestarday, the car had magically been fixed :O i saw her and him in car driving real smooth

everytime i have said something that isn't OK she never apologized about her actions, like receiving half naked pics from other man wich she showed me ''look he's in sauna'' 5cm down and would have seen his dick.

''its just a leg'' and i said I'm not OK with it

when i saw a text pop up from her ex when she was leaving for a cabin weekend, ''cant want to squeeze your boobs'', and this was on the morning when she was about to leave there, i fucking snapped threw her phone on the bed and started dressing myself, she panicked and went basically for damage control mode, ''its just his things he's like that he randomly sends anime tits and other stuff''

I should have walked out and not listened but I'm too fucking stupid and equipped with heart of pure gold

Q: So am i overreacting because its basically cheating to have other man as guest without my knowledge? even just once.

happy to clarify any stuff that you ask

Edit and she suddenly stopped saying our special good night / good morning text around last tuesday.

Edit #2 Well Well Well i decided to download Tinder and Badoo, and guess who i find almost immediately after few swipes.. Her. just 1 picture and small description.

Edit #3 15:30 I'll now leave to go outside with my dog, to clear my head and process your advice which is pretty strongly to leave her, which i will do, it will still hurt me, but it's a pain i need to endure.

Edit #4 Alright just got back home, there are some of you thats saying ''bait post'' ''not real'' etc. I completely understand why you would say that. I can admit i was blinded by love, did all the things for love and received nothing in return... I'll answer the mature comments

Edit #5 Some are saying ghost her, that's just no from me, Im man enough to go say it to her face. I already texted her that we need to talk. even tho only talking will be from me, not listening a single word she says since they're just lies.

Edit #6 It's done. went there, took my microwave, air fryer, tv, told her that your new audi guy can buy these for you and i shut the door.
