For the past two years,I've been having an affair with a guy I work with. I got pregnant a year ago and had a beautiful baby boy.I've never asked him to leave his wife or anything like that. He's an older man, in his late forties and he and his wife have never been able to have children, even though they've been going through IVF as recently as six months ago. He's on the birth certifcate, my son knows who his dad is, he was in the delivery room with me, cut the cord, pays me child support and comes around and sees my son and even spends holidays with us. He's a good dad and we still consider ourselves to be in a relationship,but recently the guilt of what I've done is starting to get to me and I have no idea what to do. I love him and I could never regret having our son,he's the best thing that's ever happened to me, I just can't help but wonder how I got into this situation.
EDIT: After reading all these posts,I realized the right thing to do was to come clean to his wife. I called him this morning and told him that we could not go on like this. I did not tell him to leave his wife,I told him that he could always be a part of his son's life, but that I could no longer do this. He showed up at my door around eight o'clock tonight with bags full of stuff. He told me that he came clean to his wife and that he will be starting the divorce proceedings first thing in the morning. For now he is staying with me, I do not know for sure what his plans are or what our future holds. I guess we will just have to take things one day at a time.
