Help me im confused :(?

I really love this guy, we have been together 2 years but we have problems. He hurt me a lot in the begginning and I can't move past it amd because of it I know I am unhappy because I break up with him all the time while before he hurt me I used to be the one fighting for him. Well, I left him and I am moving away to live back home. I am devastated at what I am doing and I am having second thoughts and want to go back but I know our relationship isn't that healthy. Its great until I start thinking of the bad stuff and then I just get moody towards him and irritable. I am heartbroken, this isn't my first breakup but guh I literally cannot picture my life without him...am I wrong for moving and breaking up?
