One of the reasons this is what we are considering doing is precisely because he refuses to have NO contact with OW and still feels he cannot commit to marriage. I used the "I'm not willing to be in an open marriage" line from one of you... (thanks)and that's when we started to discss separation.
I am thinking it is going to make this go public a lot faster, which means he will have to deal with consequences of that to our kids and everyone else.
I don't know what else to do in a sitch like this?
