Is it normal to dislike yourself cause it doesn't attract the type you like?

So I feel like my type of guy wouldn't like the type of girl I am and the guys I don't like are attracted to me. It sucks. So I try to be the best version of myself to attract the type I like. My ex boyfriend was completely my type but I have a feeling I wasn't his type, hence, one of the reasons why we broke up. He always said how crazy he was about me and that he knew he was lucky to have me but something in me told me I could be a better person for him. I mean some of his reactions and gestures would portray he was turned off by me and whenever I would see someone who he might like, I'd get frustrated and jealous. Now that we're over, well I still love him and I'm still hopeful for us to get back together, but now that Im single, I know Im going to be getting guys hitting on me but they're just the wrong guys. The types I like are just not attracted to me even though, Im not easy to like and fall in love so itll be a really long time til I fall for someone like I did for him. I just wanna use this time now to work on myself and be the right girl for my ex.
