I'm 20 he was 24 and we were together over a year. We broke up 4 months ago due to super unclear reasons but I think it was that he wanted someone else. Prior ro that he really treated me horribly and I let him get away with it because I didn't want to lose him. This is probably for the best because he's not getting anywhere. He just got fired, has a deadend major, and still lives with his parents. We also just had different future plans. I'm a realist and he is just too much of a dreamer. Anyways he was a horrible person to me and I still can't seem to let him go. How do I let him go?
