EC you are doing a pretty darn good job, I just think you need more confidence here, you're hurt and scared and frustrated I get that, but its NOT HELPING you to act on it...

This is the time to be an adult, a parent, a partner in marriage... not the time to get scared and back down or worry...

your husband is not filing or pursuing divorce.. He's just "cake-eating"... an expression we use here on this forum to illustrate marital exploitation.. that is.. he wants to "date" and to be "married" at the same time... and you are allowing it

Exposure and getting closer to friends and family, educating them is how you get that dealt with...

How is your exposure group doing? So they know your husband is cheating on you, but they aren't saying anything to him? No one is contacting him and giving him a piece of their mind and telling him to knock it off?

What is the response of your exposure to your exposure group so far?
