New to this forum, but I am in desperate need of support. I just had the worst weekend of my married life as a stepmom. My 20 yr old SD came to visit and was supposed to be here to help us while we pack for a move and help watch our 3 yr old whom the SD has shown little interest in since her birth. I have had past negative experiences with the SD, but this one has caused massive marital problems leaving me questioning the future for me and husband. I picked up the house phone to call my husband and heard the SD telling my husband's x and her mom, lies about me and my 3 year old. Of course, she lied about it and when I confronted her about lying about the phone call, she called me a horrible mother and my child a loser. She then proceeded to tell my husband more lies, which he believed and he confronted me hostily about her lies. I told him she was lying but he clearly took her side. SD also had an outburst in front of my 3 yr old calling me a F----- B----/ The two of them proceeded to have a great time together for the duration of her stay, while I had to fade away into the background and avoid the SD. Thank goodness for the guesthouse or I don't think I could have survived the weekend. This is not the first time my husband has sided with his children when they are dishonest. It has truly made me question our relationship and whether or not I can be a part of this family. Please help. I spent most of the weekend crying, feeling ill, massive insomnia and anxiety over our future as a family unit. The SD leaves today, but we are left here to pick up the pieces. Help!
