I think you have now exacerbated the problem to the point that you need to include your husband in on what is going on with you. He has a right to know that his wife is now struggling with her feelings for another man.
When I read that, I first cringed and said to myself "but I'll make things worse, maybe he won't forgive me, etc" But that is not the truth. The truth is I fear he will shrug it off, not make a big deal out of it, ignore the issues once again. It would hurt mew more than him telling me F off.
So I push, and I test, and I still get no response from him. That is not what I want in a M partner. It kills my soul.
