PMS, More Talk of Divorce, More Tears

I don't think I can handle my situation anymore. My wife says she hates me all the time and has nothing but mean things to say to me. She says she wants to leave, she wishes she never married me, and she has nothing but contempt for the person I am. She says if I don't become a completely different person, she will continue to hate me and plan her escape. She said to research online how to be a husband. 

I had to miss work today. It got late because we were arguing about an argument we had last night in which she said that all day long she sits there in bed and just hates me. 

I give up. I am not inhuman. She says I am not a man, that I am soulless and don't do anything for her. Although nothing I did triggered this round, it is the stuff that I have neglected or been too busy to do that she is bitching about now. And she attaches all kinds of mean statements to anything she says, to where I can't address the real problem, and I have to confront all the mean things she is saying. And to do this is arguing, which is a no-no. 

So, all I get is a wife who thinks I am a jerk, even though my life is devoted to trying to take care of her the best I can. I wake up and empty her commode, I make her breakfast, help her in the shower, make her bed, do her laundry and do any little thing that she asks. I don't make a fuss or get upset that I have to do this, it has become my life to just take care of her. 

She absolutely does not think that anything I do is worth a damn and tells me every day. She says she'd be out F***ing someone, anyone else if she were not disabled. She tells me these things knowing that it will hurt me and then tells me to be a man. I don't know what kind of man is expected to take all this abuse from someone who they love and care for. 

I know she is not OK. Her MS has fucked up her body, and now it is going after her mind. I can love her for the person I thought she was when I married her, but she tells me she hates the person she married and has nothing but regrets. 

Divorce is horrible, and I don't want it. It doesn't solve anything, it is just 2 people giving up. I don't want to give up, it's just that I don't know if there is anything to save. How do you stay married when the person you are married to hates you and everything that you are? Anyone reading this? Didn't think so...
