Should I have to go to all my husbands family get togethers?

My husband comes from a large family...12 children. They are into get togethers for everything...showers, holidays, card parties, 2 reunions a year, etc. There is something twice a month. I come from a family where it was just my sister and I and we very seldom got together for anything but Christmas. My husband is very angry with me because I do not wish to attend each and every one of these outings. I am an outdoors person, hunting, fishing, hiking, gardening and there isn't a one of his 6 sisters or sister-in-laws that have any of the same interests. All they want to do is shop. and this is all they seem to want to talk about for hours. It is very boring for me! When I try to have conversation about my life, they all but shut me out. I have only been in this family for 10 years. The card parties are for the men only...women are not allowed, so they sit in the other room and talk for 6-8 hours. I cannot sit that long! I do go to the reunions and some of the weddings, but that is plenty for me. Is it right for my husband to get angry with me for not wanting to go to all of these outings. He says that when I don't go his family thinks we are not getting along. I work a full time job and only have weekends for myself and the things that need to get done around home.I rarely have time to visit my 2 children. We have a blended family, but neither of my children or their family are ever included in any of these get togethers.We do nothing together as a couple alone. I am really sick of arguing over this. My husband will not talk to me for days when I refuse to go. I would really appreciate someone elses thoughts on this. Thanks
