I hope this is the right subreddit where to ask, otherwise please kindly help me learning where to post this!

So basically, provided that I'm lesbian, poly and in an open relationship, I need help navigating my current situation. Two girls, exes, and my indecision.

I (F34) have met these two, Jessica (F35) and Alice (F27) two years ago. They were together for two years, then sometimes around 2021 Jess broke up with Alice to get with her current gf. Today they are still friends, they text/speak almost on a daily basis, although they're not confidants. Alice hates J's new gf, as she is convinced she "stole" Jess from her, and although she recovered and they are now platonic friends, she suffered a lot when J. dumped her 4 years ago.

I met them in a meeting in my city between queer associations, and at the end of the day I was very happy of having made new friends. So, when Alice asked me out alone a couple of months later, I wasn't prepared to her inviting me to share her bed. Nothing happened that night out of my stoic resistance, as by then I had learned that she was in a relationship and I didn't want her to cheat. But the sexual tension was crazy!

After that we kept on orbiting one around each other and texting like crazy. I was strongly fascinated by her, but it was forbidden, and eventually we reduced our contacts. Today we are platonic friends and we text around one or two times per month.

Now, Jessica... She's more mature, and by far the hottest one. She's very secretive and I learned she's Alice's ex only because A. told me the full story. Jess captured immediately my attention, but she kept more distant from the very beginning. While I was texting and flirting with Alice she was just sharing a meme, writing a "hi!", stuff like that... Until last June, when she was visiting again. We kissed, and from then on we started the most crazy situation I ever found myself in.

Jessica has a girlfriend, and she's basically cheating on her with me, so we're keeping our situation secret from everyone, including our circle of friends. We're ldr, she's in another state and we're meeting roughly a week every one or two months, to have the most mindblowing sex ever. I'm crazy for her, but at the same time I'm not jealous of her relationship, I don't mind how she manages it nor I want from her anything more than what we have today.

Alice called me two weeks ago to casually mention that she's opened her relationship, which means a lot to me. She hasn't asked me out yet, but I can anticipate that something's in the air, as I haven't forgotten that night's crazy sexual tension. And I'm sure she hasn't, too.

But I'm currently very happily involved in this situation with her ex gf, which makes me wonder if it's a good idea to start anything with Alice at the same time, either that being a one night stand or something more.

Moreover, Jessica is sending signals that she's catching feelings: she told me that she's jealous of me although of course we are not exclusive, she told me that she's not having sex anymore with her gf, etc. We even talked about Alice and she anticipated that she expects her to hit on me sooner or later, and she told me that she would be jealous of that. All of that provided that, as she's in a monogamous relationship, she very well knows that she's not in the position of asking me anything.

I also can't deny I'm catching feelings for Jess, as the sex is amazing and she's so hot, and we have a lot of things in common, and this is impacting my other situations. So I think that maybe spending a night or two with Alice would help me balance all relationships better, including the one with my primary partner.

Of course, I've been attracted by Alice since that night one year ago. But at the same time I don't want to ruin anything with Jess and I don't want the two of them to be jealous, or to suffer. I'm sure that would happen if they knew one of the another.

I'm conflicted, what should I do?
