I have no idea where to start. My husband's ex messaged me telling me she envied me because I married him. She messaged him telling him she still loved him and wanted to be with him. He as politely as possible rejected her and told her he loves me. He politely explained that she had her chance and she messed it up by cheating on him. My husband has to deal with her because she is his best friends sister. Like before they broke up he went to his best friend and had a long conversation with him about how and why he was breaking up with his sister. They remained friends and now his best friend and I are good friends. Anyways, how am I supposed to respond to her? I visit their family twice a week because we are all close... She was married, but her husband cheated on her and now she has a baby from him. She keeps talking about "Oh when I was dating your husband we would always go to the movies and out to eat." And she keeps bringing up memories from their relationship. It doesn't bother me. I just don't know how to respond...
