12 years of marriage. Have a 7 year old baby. Recently found out my husband is cheating on me since 5 years. After 3 years of marriage his mother had moved in with us after her husband's death. There used to be fights because of the politics played by my MIL.My H always took her side. They were emotionally married to each other.I felt like outsider. Slowly he started silent treatments, stone walling and started to be distant. I was in all love with him. In 2022, I caught him cheating by talking to a lady on phone for hours. I was devastated. He didn't give me any detail. I knew it was more than talking. He promised he will never repeat it. Then we moved to USA from our home country. He promised he will rebuild. But recently found out that he never stopped talking to the AP. He used to go to our home country every 4 months to have honeymoon with her by claiming he is going to meet his mom. The AP is a massage lady who used to work in spa and he had went for massage in 2022 when I was in my maternal place for few months. She is a divorcee with 2 twenty years old kids. He gave her a huge amount of money. Set up her own spa business. Sponsoring AP's daughter's higher studies, took a loan for a house she wanted to purchase and claiming that she would have paid the EMIs. Whileas he gave a huge down payment for this too.
This is a 2nd time betrayal. He was very cruel to me these few years. 5 years affair. So many big things he did for AP.
When I caught him, he is remorseful and want his family back. Want to be a better person and love me the way I want. He is a small narcissist and excessive avoidant. He says he was poisoned for me by his mother and we didn't solve the issues and he had resentment baggage. His ego kept him talking to me about our marital issues. He wanted to help the lady to pull out of her problems and poverty and strayed. (FYI-He is a good person at heart.)
Please suggest me. I am devastated.
