My husband got his affair partner pregnant and she gave him an ultimatum to divorce me if he wants to keep the baby or she will have an abortion. We were in the process of moving this past June when I discovered the full truth of his affair and their expecting a baby, she was barely a month pregnant. My husband chose to be with her and stayed in our old home. As soon as we moved out she moved right in. Over time he started reaching out to me and our children and agreed to do EMS Weekend with me. During this time his affair partner went home to a different state for a little over a month and my husband and I were making strides in understanding our situation and our marriage. We were able to reconnect and have honest and open dialogue. However, about 2 weeks after EMS Weekend, his affair partner moved back in with him where she is currently residing. My husband has committed to completing our Beyond EMS course and staying connected with me. How can we truly move forward if he is still living with her and now it seems as if we are in the situation where I now feel like I am the "mistress?" Is there still hope? Is there anything more that I can do? Or should I let him go and focus on my own healing and recovery?
