Does he really want to be with me?

I have been married for 10 years now. I still feel like I do not know my husband. (We have been together for 13 yrs) Everything he does, is about him. He used to love fish tanks. Spent thousands of dollars of a salt water set up. Now, he is into this game World of Warcraft. It is all he does. Wakes up, checks his auction. Comes home, eats dinner, plays his game until 1-2am. We have 3 children who are 9, 7 and 3. All boys.
I feel like a single mom most of the time. And just want my husband to "see" me.
In out total of 13 years together, he chose 1 date for us to go on. Our first date. I am tired of being the "boss" and now, I am tired of being so unhappy and alone in a marriage.
What should I do?
