I do not like staying with my BIL and SIL. Suggest!?

I and my husband stay with his younger brother and his wife. We got married about 2 years back on the same day as they got married. Even before the marriage I knew that all 4 of us were going to stay together. Though I felt that I was compromising, I went ahead with the marriage and adjusted to life with all 4 of us in the same house. I thought things would change post marriage. But near on 2 years, it is still the same. I feel that my husband is reluctant to emotionally commit to me wholly because of these strings attached to his family. We have a lot of fights as a result. And when we do, I feel distanced from the family whereas his relations with BIL and SIL are fine. I feel very cut off and depressed whenever this happens. Things are not good between my parents and my in laws too since the beginning, which is an added source of tension. Also my MIL favours my SIL over me, which hurts. And my husband refuses to listen to me when I tell him these things. All these things are affecting my life. I am not sure how I should convince my husband or what should I change within myself. Any suggestions.
