This is a long story that I'm probably going to be called a faggot for, but hear me out.

I'm in university. Recently me and my classmates (in my part of the world uni is just like a school, except for adults) hanged out together and, after getting inebriated, played some games that ended up in me making out with two girls who are in long-term relationships (so am I btw). They are both obviously attracted to me, what I'm trying to figure out is whether they'll act on it.

Next day in university one of the two girls is being playful and even jokingly proposes that we all meet up again. The other one avoids the topic (she's engaged) so I figure she's not up for it when she's sober. Nothing happens, everybody leaves. I chat up the first girl in the evening, she's flirting with me, we promise to give each other \"uncomfortable\" looks the next day (I know, child's play, but keep in mind we are both in long term relationships and everybody knows it. My girlfriend studies at the same uni but she's currently abroad. Neither of us can afford more than a mild suspicion).

Next day I do just that, she's obviously enjoying it and she's always the one to look away first (I keep my eyes on her long enough). After a while though she looked a little bit uncomfortable, or so I interpreted it, and I stop doing it. While in class I text her saying something along the lines of \"Can't take it anymore? ; )\".

We move on to the next class and don't speak of it. 20 minutes later she reads the text and texts me she wasn't embarassed at all (a lie) and that I didn't have the courage to say it to her face (the text I had sent). I tell her we were in class, she tells me I could've spoken about it in between that class and the next one.

(I didn't talk about it during break because there was no moment when we were alone.)

Class ends, I tell her she looked like she'd faint (when I was giving her looks, implying that she's the one who needs some courage. She acts like I'm exagerrating and makes sound like it's an excuse of mine (obviously still trying to say that I lacked courage.))

We then leave each on his own way.

Hoe badly did I fuck up and what would you do?

My current plan is to be a lot more direct tommorow (god, ands I thought I was overdoing it) and kiss her if we manage to find some goddamn privacy, but that's precisely the problem.

Tl;dr I thought I was rushing but it turns out the girl thinks the opposite, implies I lack courage. We see each other in uni but we are both in long term relationships so we can't express the attraction. What would you do?
