Little Boy Husbands

I married the typical LBH (Little Boy Husband). He expects dinner to magically get done, doesn't think making dinner or helping to make dinner is his job. My other big peeve - he thinks that whenever something is gone, I should make sure it's re-stocked, without anyone telling me that the item was gone in the first place.
Case in point, just this week alone. Monday he tells me that the milk is just about gone, but then has a fit when I don't have some in the house on Monday night and I tell him that he can't drink any because I need it for my breakfast and there's other things in the house that he can drink that I can't. You know, we both are pretty much working 5 days a week, we both have the same hours on the weekend (and typically he has more because he doesn't often do VB stuff)
Tonight we have a fight because he said he would make dinner and then comes home and tells the kids that we have some time before dinner because I haven't made it yet. After dinner, he takes off to Sam's even though he knows that I'm going on Friday. (LBH passive-aggressive bull shit)
I had a friend on Friday ask me why I'm married to him, and honestly, I don't know why. It's been over 3 months since we had sex, I don't find him physically or emotionally attractive anymore, and we generally don't like each other.
So, why do we stayed married? It's because we have kids that we can't tollerate the idea of not seeing everyday. I can't afford to be a single parent and give my 2 kids the things that I want them to have. The money is likely the bigger reason. I like my house, my parents gave us 20K so we could have this house - house prices are so high, it would be hard for either one of us to afford a similiar house.
I can't believe how terribly lonely I am. I would rather just be alone that be lonely. Every night, he goes downstairs and watches TV, I go to our room and watch TV, take a bath and go to bed. My life is my kids, sadly, its that pure and simple, there is no me, there is just them...
