Let me tell you, this is the most immature and misguided idea I have seen in a very long time. How old are you? 17 or maybe 15 years old.
If your husband cheated on you it was because the relationship isn’t working for him, and I would gather for you either. So, the question becomes one of what needs to happen to either heal it if you are BOTH willing to do the work to make that happen or dissolve it since he is no longer interested.
One cannot force another to love them, nor can one have a healthy relationship with someone who isn’t interested in being involved with you.
If you really loved him, you would let him go.
I know from personal experience as my ex decided that he wanted out of the marriage and left. It was not easy, but I would never want to be in a relationship with someone who didn’t want to be with me any longer. So, I gave him my blessings and we went our own ways.
Was it easy? Hell no! Was it necessary? Yes, indeed and it has allowed me to regain my emotional and physical health, because I wasn’t happy in that relationship either – how could I be with a person who didn’t want to be there and let me know it through his own anger and resentment till he had the courage to finally ask to be released – and now it wasn’t pleasant, but we came to terms and we are now better friends then we were married – that is a fact. I have the freedom to go and do what I want and he is remarried for whatever that has done for him. Each for his own to choose.
