My husband had a 4 year affair and fathered a child with his affair partner. D-Day was 18 months ago. He says he does not love the affair partner but maintains contact for the sake of the child. His affair partner hates my guts and has said she will never allow me near the child. She refuses to contact me for the child's needs but aggressively pursues my husband. He has communicated to her that he wants to work on his marriage but she responds by insulting me. I do not feel safe as long as he is in contact with her. I feel he must choose between our family of four children and his affair partner and her child. I am struggling to heal with the way she continues to contact him and his refusal to cut her off. I have asked him to move out. What is a realistic way forward regarding the child and healing my marriage?
