Do you blame yourself for all your past failed relationships?

For me, there’s a little voice at the back of my head that makes me want to feel guilty about it not working out with all of my exes. After all, how can I be right and ALL of them be wrong? I must have some flaws which probably fucked things up. I’m trying to work on them, but it makes me wonder if I’ll ever find a girl I can get along with to keep around for a while. And yet, at the same time, I feel like I want and don’t want something like that too. Life is complicated, but time heals all wounds
