Does it really matter WHY he is mean to you? It could be mental illness, alcohol, meth, abuse he suffered as a child, ...

I was in love with a Jekyll and Hyde. The good was wonderful. The bad was horrific. You want them to be the good person you know they can be and stop being the angry person that upsets you.

You cannot control his thoughts and behaviors. You cannot change him. You can only change yourself.

I am sure this is not what you want to read. You want to know how to get him to return to the man you fell in love with. I have been there. It did not work out for me.
