Last year i dated a guy who had previously been a friend for a few months. We broke up because once I started dating him I noticed things about his personality that i hadn't seen as a friend. He often came across as selfish and lacking in empathy, and there were times when he didn't seem to have any interest in my life. We also had quite different long term goals.
Now he is dating someone new and either she is dating a different version of him to me, or she is incredibly tolerant and prepared to overlook all the things I had a problem with. However, whenever i hear about them dating, usually through mutual friends, I get jealous. For example, they are going to the coast this weekend, and as soon as I heard i thought, why can't I have a fun trip to the seaside with him? I don't want to date him again, but I feel like I wasn't good enough as a girlfriend because he now seems to be treating someone better than he treated me.
