Why isn't my man there for me?

My man expects me to wait on him, cook, clean. In other words be a super mom and wife. Even if I am sick, I have to comply or I will be given the silent treatment. Or, he just casts me aside, example he doesn't invite me on plans he made with our girls. Last night I had car trouble, when I called him he wasn't interested. A good samaritan helped me out. It's not the first time. I always have to count on someone else. It seems that I am only there to serve and not ask anything in return. I often think that when I am older, who am I gonna count on for support. I am seriously thinking of leaving him. His attitude saddens me.
