DH has gone and got himself a mistress - not in the sexual sense yet, I think, but in a kind of faux-romantic kind of way. He doesn't know that I know. I found out through a bit of digging, as my spidey-sense was alerted through seeing the way he is with her. Because I've been with him so long, and for a few years we did a bit of swinging, I can tell when he fancies someone. Anyway, a techie friend of mine gave me access to some communications between DH and OW and she sounds like she's fallen for him. I don't know her personally, but she sounds like a decent, middle-class woman, perhaps a bit naive, but certainly a caring type. Reading his messages to her, he sounds like a completely different person! He also sounds very caring, a family man, who does nice things, and seems to think he's found the passionate love of his life! Because of reading of this strange version of my husband, initially I thought that maybe he'd fallen for her too. But our sex life hasn't changed, and he's been hinting about getting back into swinging. Other than the messages, I can't see any evidence that he's in love with someone else, unless he's developed the ability to adopt two different personas.
I'm feeling kind of sorry for her, although I don't know her, because she doesn't appear to know what I consider to be the real person he is.
Oh, and for you caring guys who worry about me being in an abusive relationship - don't worry! I'm not a victim. I'm a fairly easy-going person... and I am making my own plans 
Anyway, my question is - please say I'm not weird to feel a bit sorry for her and should I just forget about her?
