My boyfriend and I have been together for a little over 2 and a half years. He is 23 and I'm 24. The age played with us a little at first, causing fights to be atomic. 

Now, after we've separated twice for personal reasons, we are finally in a place where we both can admit that we want to spend the rest of our lives together. 

However, he over reacts like a toddler. Every time we fight, he still shoots to that atomic level that makes me feel stupid and like complete shit. I hate it. 

I know he has a lot of self esteem issues, internal struggles with his faith, and his body image doesn't help either. But I don't understand why it causes him to lash out at me when we aren't all "lovey-dovey." 

Am I missing something? Are his internal demons really messing with him that much? Is there anything I can do to help him? 

Or

Is my guy just 100% an asshole?

Willing to answer any questions anyone who is willing to help may have.

Anytime we aren't being sickly sweet to one another, he's busy being a huge asshole.
