What would you do if your husband said he was ashamed of you to his parents?

My husbands parents are visiting from colombia they are in their 70's. They meet me before 6 yrs ago when I was pregnant. They pretty much are here to meet their grandkids. My sis in law and I had girls one wk apart. His parents are staying at my bro in laws house. I dont have motivation to go and meet them. My husband is like we cant upset them old and only staying two months. He wants to paint a good picture even though were having marital problems. Extra facts im white and dont speak spanish so its hard for me to comunicate anyway. My husband doesnt want to translate. My sis-n law is hispanic and they dote on her. My husband brother is keeping it a secret she cheated on him last yr when he was deployed and she had an abortion Seeing them kiss her but makes me sick. Meanwhile I have done nothing to my husband but he's ashamed? I think weight gain Im 9 yrs older than my sis in law. What would you do in my case? I feel like im vilinized because im white. Not that they think ive done anything but if ot came down to me or her I know they would think I was the bad one.
