I would just urge you to take a breath for a moment- D is a huge deal. I think most of us on here have to deal with infidelity. It's horrible! We know, but maybe take a look in some of the other forums, talk to a DB coach, go to IC, something to help you process it all before you go down a path too hastily.
You don't want to have a huge regret when this is all said and done. We all have been where you are- it gets better with time.
I guess I'm just urging you to give it some time before you act on anything.
Hang in there!!!
