I am a prisoner to my husbands ADHD

I am very upset this morning, like most mornings my husband has raged at me after raging on our son.  My husband who has ADHD, has been yelling at me because I made one small comment about not liking to clean up. My statement wasn't directed at anyone thing or even him, just something I said, like a person would say "i don't feel like going to work today" even if they like their job.  He swears at me and uses foul language (with our kids in the next room).  I am tired of his angered rages that I am the target of.  He also rages this way with the kids when he doesn't nderstand why they are doing whatever it is.  I feel bad for me and my kids.  I feel like we have to be the target for all his anger and frustration because he has not been properly managing his ADHD with therapy.  According to him, I am the problem person with all my negative comments.  Funny thing is, I tiptoe around this man and do almost EVERYTHING for him but wipe his butt.  Not only this but I am full time nursing student that takes an enormous amount of time and energy.  I feel like I can't go on in this relationship and feel like my needs will ever get met.  My needs may as well not exist because my husband doesn't even seem to know or care that I have any.  He constantly tells me I am criticizing him, when I am sipmly asking him to take care of things he has not followed through on.  I feel like I am a prisoner to ADHD.  I have left him twice but he always seems to "win" me over by being extrodinarily nice and helpful.   I tried to make our marriage work because I love my husband and we have a family but what kind of family is this?  What kind of existence is this for me and my sons?  If we arent together, how can my husband be a father to my sons?  I do everything and he refuses to get on any sort of schedule, when we were seperated before he didn't get the kids to school on time, didn't pick them up on time and didn't make them go to bed until late as 10pm some nights.  I had to stop letting the kids go over to his house because of this and I am afraid that this will be how it is if we divorce.  I am tired, tired of even having to think about this.  I just want a normal life again.....not that things are ever "normal" but people who are married to someone with ADHD knows that only someone who is not married to someone like this would ever even say that......
