Ok, my sister in law got married. We have a small family it's just me my husband our three kids, her and her mom. They don't have any other family. There dad or his side of the family are not part of their lives. So when she got married I felt left out because she included everyone else but me. So I messed up and threw a fit and did not want to participate in the family photo. I ended up taking the picture. Now I feel so bad and apologized twice, I should not have done that it was her day. Well now she is giving the cold shoulder four months later. She barely speaks to me, it's so sad because we used to be such a happy family. Well, now my mother in law is furious because she is not speaking to me. My mother in law confronted her (her daughter) and she yelled at her and told her that I embarrassed her in front of her friends. Then she told my mother in law that this is none of her business, and she better not ever talk to her that way again. Now my mother in law said she should just cool off and come back into the family when she is ready to forgive. Any advice on how I can fix this? This is all my fault because if I didn't do that at the wedding, none of this would be happening.
