fiance isn't happy anymore.

My fiancé isn't happy anymore. He told me last night he didn't know if he wanted to be with me anymore. For the last month he won't spend time with me, he hates having sex with me and everything. Since we have been together I flirt with him and give him my attention. I cook, clean, do his laundry and let him buy and do whatever he wants. The thing is he has anger issues out of this world and makes things hard for me. I'm a stay at home mom and my son is disabled. I'm to the point where I just want to move back home and break up because of this.
