My husband & sister

Almost a year ago I found out that my husband and sister had been having a fling. They both say there was no sex. Just talking and kissing. My sister was living with us because she had no where to live when it happened. She told me about it when she was mad at me. She admitted she only told me to hurt me. She said that my husband told her he couldn't have sex with me because of my weight. He denies this. She post things about all this on her social networks. Even now a year later. I can't get past it. I have 2 kids with my husband. It has really put a strain on my whole family. I think about it daily. Especially during sex. I think about the weight comment. I guess my question is how do I get past this? I want to be happy again.

ask your sis to leave and take marr coun with your hus, if there is still cheating you must think of leaving
