My Girlfriend and I really like each other, but i feel that it might be getting complicated, IDK what to do?

So we have told each other we love one another, and we do. But recently I feel that we are finding less things to talk about when we are texting or something. When we are in person it is a lot easier. I really like her and if I really think about breaking up with I start to get all teary and can't even really imagine doing it. Also in a few weeks there are some formal dances coming up and she says she is excited for them and I am to, but if we were to break up I would feel like a complete jerk and ***. Not only for really hurting her, because I know she still really likes me, but also for doing it right before dances. And she wouldn't have a date then to go to them, also we have already talked about our proms coming up and that stuff, I even know how I am going to ask her to prom, kinda a little showy way at school. I am excited for that and she is too. Also when we started dating she was kinda into a little PDA and I wasn't to much. Now though I am OK with doing some occasionally, but now it seems she isn't really. I just don't know what to do, I just want answer kinda like it will get better or something. I just can't really see myself breaking up with her. Just need some advice please.
