I know that information from the W and from his facebook page. As far as financially, yeah...cellphone, car insurance, car payment...basically I still take care of the bills I took care of before.
DC,
I think the possibility is very strong that he is lying to your wife about the D thing, or at LEAST exaggerating it. He certainly wouldn't be the first one to lie on Facebook, and in adulterous relationships, BOTH parties lie nearly 100% of the time, so just factor that in to your decision-making somewhere.
As for the finances, I'd suggest that you immediately end any financial support that directly enables her affair. The cellphone would be the logical place to start, and I would let her know that "I will no longer financially enable your affair. I can't stop it -- that's your decision, you're an adult -- but I damned sure won't pay for it."
Entitlement is a huge undercurrent of affairs. If she wants to be a grown-up here, she can start by learning that she's not entitled to have her husband support, financially, all of the things that he did when she was committed to him.
