Uh yeah, I had an online (nonsexual) relationship with a female... My (now ex wife), discovered it, and even though I tried to keep things together, she divorced me over it, even against the advice of a counselor or two. When I say nonsexual... I mean that we never discussed any of that stuff online... just pretty much discussing news, our kids, and our daily work experiences... internet pen-pals so to speak.
My Ex is a hot-headed Irish girl... That was 17 years ago... she is still bitter etc. She'll never let it go, yet if she did or could, she'd be a happier person.
Whew!
