So me and my girlfriend just recently broke up. I thought that we would last longer but her family is moving (they are only moving like an hour away). I didn’t see that as a problem, she did. I was on a trip to a different state when she asked me to come back home, and being the loving person I am I did. When I finalized coming back she broke up with me. She went on to date her guy best friend about a week and a half after. I’m not sure what to do and all I want is to cry myself to sleep. What should I do.
