I haven't read all the messages on here, but thought I'd give my perspective as an OM in an affair - do all OW/M have the same delusional thinking that their part-time partners are telling the truth, the whole truth so help them....
It started off as messaging as friends (I guess as so many do these days...) with contact getting more and more frequent. When did it start becoming flirtatious? Good question, I can't recall when exactly and certainly no conscious decision to start with. Well aware she was married with children never saw the route the friendship was going down.
Then come the messages about how her OH doesn't listen or care about XYZ and that I'm the good listener. Conversations stray to What-Ifs? and regrets.
Although we would meet up in a group of friends, the suggestion then that we go somewhere together to go out, just the two of us. No outright mention of it being a date, or anything more than friends wanting to get away from it all for a night. Yes, it was overnight. Yes, a certain amount of discretion was advised.
That's when the affair started. Yes she was still married, claiming she wanted to leave and that yes (as the article) no sex had been had for X years.
Did I believe what she was saying to me? Interesting that most on this thread think that it's all a load of rubbish from the married person. It is difficult to know for sure though, what are you going to do? Stalk them and watch through telescopes....? You have to believe, not because you don't want them having sex with their partners, surely part and parcel of affairs really, but because you want some honesty in-amongst all the lies and deception.
Did I think of her husband or children through the affair? In all honesty, not really, why would I? I was enjoying the relationship. Yes it was in snatched times, but you don't go into a relationship and see them every day from the get-go anyway.
Do I think OW/M are evil, or nasty for doing what they do? I don't know really, yes they could not start the relationship and stay alone for a bit longer. Could they wait or pressure them to leave their spouse? Possibly but wait for how long? Or pressure them and risk resentment? All difficult choices and especially when they are the greatest thing to happen to you.
Love makes you forgive or overlook many things.
