I'm 17 and my ltr is 16. Lately there have been more and more fights and less sex. Recently I found out that she was texting a dude, pretty lovey dovey shit. She told me she could stop if I wanted her to, I told her It was very weird but it's her choice. She didn't stop and it looks like they are pretty close. I broke up with the bitch. Should I have proceeded differently? Do I focus on myself now or do I try and date other people right away?
