What you're feeling is valid. I know it wasn't a healthy relationship but eight years is a long time, especially since the first years were fine. Eight years isn't something easy to move on from where you'll feel okay instantly. I think it's even okay that you remember the good times as long as you don't ignore the fact that after the good times there were unhealthy times as well and that you didn't deserve to be treated like that. I don't think there's a right/wrong amount of time to move past a relationship like this.
