Speaking from experience drop the phoney email NOW! Do not respond to him again and don't let him know that was you.
You realize there is a problem in your marriage. Focus on that. If you can tell us more about your relationship. Has your H expressed unhappiness? What led you to look for him being unfaithful?
Not using the phoney email won't be hard. I really don't know what else to say there now anyway. It is, however, the only "proof" I have that he is at least contemplating an affair (while I suspect he's having one online anyway).
I'm sure there are a lot of things about our relationship that might have indicated a problem a long time ago. But, since this is my first "real" relationship, I probably deluded myself.
I'm not sure what led me to think he was being unfaithful. It is probably my own insecurities. But lately it's probably blatenly obvious to anyone else...
Anyway, yes, we have problems. We have not had any kind of physical relationship for a long time. I've tried, but get no response from him. I also have some health problems that make it difficult to be intimate, but I know that I would respond if he showed any initiative...but he hasn't. I'm trying to get the health stuff "fixed", but it isn't easy. And I'm afraid I defeat myself when my insecurities are that he doesn't find me desirable (because he doesn't respond)...its a vicious cycle.
I think he also thinks I'm a bit of a prude. I've asked him about his fantasies, but he says he doesn't have any. I caught him looking at a bondage website the other day...that was kinda the tip of the iceberg for me.
My husband doesn't work. I am the sole provider in our household.
