Getting Back with an Ex

I've dated my ex boyfriend for 2 years. We've had a few breakups, but always find each other again. I was going through some things and decided it would be best for me to move out and find myself and my own happiness. Over the few months I've been gone, I've gone on a few dates but I can't shake the feeling that I made a mistake leaving. No one gets me like he does. He makes me feel at home, like I can truly be myself. That being said, advice? I'm worried about how my family would take us getting back together. Its been rocky, but I think going back into it slowly will make things better, where in the past I always just move right back in. I'd love to hear some experiences and words of wisdom
