I started fights occasionally and caused problems in our relationship (bringing up the past, insecurity, blame) when I remember those things. Now I will be the first to say that yes, this wasn’t the healthiest start to a relationship. And it sounds like the two of you have put serious effort into actually getting past things and making things work, which is good. That might help you get past the feeling that you’re inadequate, or that you “forced” him into this relationship. But that doesn’t mean that your relationship is fatally flawed, any more than it means you’re broken.
