Don't trust the OW, why would you? Just because you exchanged a few words? They've kissed once, it can happen again, words are only words, observe her actions.
As for the hubby, "pining" away for this OW he can't have.
You don't live with your husband right now?
You have been separated for 2 months physically?
Observe reality here, he wants what he can't have, he can have you easily and that isn't what he wants right now.
Currently in his state of mind, you won't be able to reason with him, you won't be able to use words to convince him that the marriage is worth working on and investing effort in.
You could work on yourself and become a better person, but that's not for him, that's for you.
Do you guys share a home? Who suggested you move out? Him or You?
