Mordred - im sorry for your situation and your post really got to me :( I have repeatedly spoken to my DP about my online friend, and one time he did what you did and read one of our conversations and he was upset (to say the very least). I told him at that time, right, thats it - i wont speak to X again but he insisted that it was ok, so long as i was always open with him etc, which i am to be fair. We are in a similar financial boat and both he and my DP have businesses - so i often find myelf telling stuff to X and then telling DP what he has said, DP will even ask me to ask him stuff!
Its a bit weird i suppose. Truthfully though, i wouldnt like it if it was on the other foot and im sorry to say it IS an emotional affair
. I would however stop it immediately if DP made his feelings clear that he didnt want me talking to X again.
I have to disagree with Anyfucker (waves madly, i used to be LEM, i bet you wasnt expecting that from me!) though.
My DP is no mug, but he is very understanding and realises that i need a friend sometimes. He seems to accept it. I think it is because he cares about me that he accepts the friendship. If i thought i were taking my partner for a mug, i would stop things immediately.
I would be lying if i said that i could give X up easily, but I would and he knows this.
Mordred - your wife is lucky to have you, and i hope she appreciates you - but you know, i think if you are that unhappy with it, you should ask her to stop.
