Should I feel guilty for not wanting to go to my sister in-law's (who doesn't like me) for the holidays?

My sister in-law can't stand me! I don't really know why but my sister in-law and I have had many issues since my husband and I have been married. Frankly she is just not very nice to me and barely will hold a conversation with me. Up until about a year ago Ive always tried being really nice. Tired of it always seeming one sided I gave up. I'm tired of her treating me like a jerk. We always have to go over to her house for holidays. She has never called me and asked what we wanted to do, what we had planned....etc... Basically if we want to see her and my husbands nieces we have to go over there. I just think it is very self centered. I don't want to go over there. I want to be home with my kids and my husband. My husband and I are fighting because he says he's tired of being in the middle. He thinks it's very inconsiderate of me not wanting to go there for the holidays. I try to explain to him that I don't put him in the middle because Ive never done anything to his sister. I want him to be able to spend time with his sister on the holidays but I also dread going over there because of how she makes me feel. Do I just suck it up like normal so my husband is happy and can spend time with his family or do I tell him I'm not going? Shouldn't my husband care and consider my feelings? I feel like his sister can treat me however she wants and he will never say anything. He always has an excuse and somehow it usually gets turned around on me.
