So confused, stressed and frustrated...

My boyfriend and I have been dating since April of this year, but we've never lived apart. It was stressful from the beginning, but it's getting even more stressful.

According to him I'm always starting arguments and trying to make a scene, but whenever I walk away because I'm sick of the crap he starts instigating and if I don't respond he says I'm being childish. However, when I DO respond I'M the one making a scene. I have sacrifice a lot for him and done whatever I can think of to make him happy, but it's like none of that matters. He's constantly wanting me to change things about me, but I've accepted him the way he is.

He is older than me by a few years and whenever I just don't feel like talking to anyone (him included) I apparently have an attitude. I like to do things on my own and I have a hard time accepting help because of not having any other choice BUT to do things myself as well as take care of other people in the process. If I protest to any help from him I get accused of having an attitude problem and half the time (when I'm having an "attitude") I get called a bitch and/or a dumbass. I'm at a loss here. What do I do?

He's asked me if there's anything he does that bothers or annoys me to tell and every time I have he only justifies it. My stress levels and depression are through the roof.

What do I do?
