Marriage

So my husband and I have been married for 7 yrs now. He has an 11yr old daughter from previous marriage. We have a 5 yr old daughter, 1 misscarige last year, and I am 27 weeks pregnant with a boy. I don't know if it's because I am pregnant that I feel like I just don't care for him. Or because he completely ignores me. I mean we both work all week, on weekends all he wants to do is bring his mom and brother to spend the whole weekend. So I am at work all week and yet have to cook all weekend for them. It's just so annoying. Now my sitter is out of town so I took off this week, so he said since you off I am bringing my daughter for the next 2 weeks. Yet the week I wanted to rest and get things done at home I can't. My daughter and her fight all the time, he does not discipline them to where they need to behave and get along. I always end up spanking my daughter when she starts to throw fits. I feel so bad because his daughter just smiles when I do. Our sex like is basically dead maybe once a month if even. Which I just dont want no more, because either we are both to tired or he has ppl over. His daughter is 11 with her own phone her mom calls her all the time. So this morning I turned his alarm off and when I did I see he had a called from her which they talked for several mins. I am frustrated for one she just got here she's 11 what can she possibly want to know when she called her too and I was here with her around that time. It frustrates me because when I asked he said she wanted to know if she was eating right and if her laundry was done. I need advise am I over reacting or what can I do not to feel like I hate him.
