Be careful what you do. I did the most devious. I set up a fake man. Fake man had a fake email virus and "our" fake emails were accidentaly being re-directed to H. Bcc.
Another Fake man, emailed H's GF as a potential client. So here I am having convo with OW#2.
Fake man got H's attention though and H, who hardley ever contacts me, emailed who is the new BF or yours!! I should tell him who I am. Ha!
The sad part is, I think H took it as a way to feel less guilty about what he was doing.
