Will this ever change??

Apparently no guys in the world are nice and they are just all rude. Not my words, but that is what I was told this morning by someone who apparently thinks that they can treat the people they care about in the rudest way possible. When I brought up that there are nice guys that don't have anger problems, I'm apparently threatening him and I should just shut up because I'm the one that starts problems.

I've put up with this for 4 years and when I say that I'm not dealing with it anymore, I get called a cunt, get told I'm running my fat mouth, get called a dumbass, you name it...but he always says he doesn't mean those names. Its because he's 'grouchy' in the morning and I start the problems because I talk to him. When I told him that he can control his anger and that he isn't trying at all to do so, he got mad and said that he's allowed to be this way in the morning.

What gets me is I'm not allowed to be moody on my period because I'm supposed to control it. I can't be grouchy at all or else I get blamed for wanting to start fights. And I know I shouldn't meet anger with anger, but I have tried being nice in return and get met with anger. I got told that I'm acting like his ex now and I'm starting to think he's been the problem in all his relationships, not the girls. Him respecting me has usually been the argument between us, and it isn't like I'm disrespectful towards him. I've helped him with money problems when I only work part time (owes me 2600 total) but apparently he's working for both of us (he pays none of my bills, I take care of all of my own stuff with my own money) and he lives in my moms house for free.

So, tell me honestly, is there the possibility that he is going to change? Or do I not even bother wasting my time?
