I just keep trying to wrap my mind around the fact that the guy I was in love with and wanted to marry , is someone I didn't know at all . People wanted me to message him and tell him off but I really didn't want to bother , so my sister who hated him did and wow , I love her . She was mean . I already have trust issues ... this definitely isn't going to help .
What may have caused your sister to tell off your husband ?
