Loving yourself

Hey guys! I know we have probably all had our fair share of bad relationships. I would like to know if I can ever trust, falling in love with someone and live yourself, after being so hurt :( I was in a violent relationship for a year. Then 6 months later I was dating another guy (for a year) that was never sober and cheated. I dont know what to do anymore. I am really into a guy I'm really scared that he might turn out like them. I dont know what to do...those two ex's made me see how cruel people can be. How do I learn to love myself or another after being through that??? I haven't felt so much hate for myself ever :( what do I do?
