Since you've been talking to OW, why don't you let her know you and your husband are still sleeping together.
Do it! I would be honest and frank about it too. "We had sex on Tuesday." No woman likes thinking the guy she's sleeping with is having sex with someone else.
Once again, do not have sex with him & get tested.
When my h admitted to me he'd had sex with someone else multiple times, the first thing I did was run out and get tested. He was defiant about not getting tested himself. As if!
