Do you argue about ?

I've been married for 15 years and he still wants it all the time. And I mean ALL the time. I work full time and take care of my child full time. I pay the bills and worried about how to make ends meet. Clean house. And he wonders why I'm tired all the time. He says he needs it and I don't. I love him, but I think if I had a husband to help me with things I would want to more. I lost 2 children and had many surgeries for endometrosis and cysts. I had to have a hysterectomy about 8 years ago. I don't even think it's about being together, I think he's just addicted to . Whether I'm there or not he's always taking care of himself. I think he has a problem and he just can't understand why I don't want to all the time. Sometimes I think it's hard to think about him that way when he acts like my child. He's a big kid. I can't see being with someone who I have to take care of.
