Welp what the fuck do I do gents?

So I just got home from being at the cinema with my ex? So me and her have had contact for 2 years on and off and only started to get romantic a couple of days ago. We both liked eachother alot so it went pretty quick. So me and her are just kissing and dumb stuff while her thirdwheel friend is watching. Anyways she gets the idea and slides my hand into her pants then immediately says that that was a dumb decision. Anyways then we go into the cinema. And the movie starts playing blah blah blah and we are holding hands and then she puts her hand in my crotch. I don't think she noticed. Well anyways. A bit later she takes my hand and moves it to her butt. I'm being annoying and squeezing it and think nothing of it. Anyways the movie is over and I go home and think nothing of it. Then I get a text from her friend saying she knows what I did and that I was disgusting. My ex then text me fuck you, you won't get another chance. I'm so confused and kind of crying. Idk if I did something wrong. I love that girl. More than I've ever felt before. So yeah I'm kind of confused what the fuck do I do now?
