+ and -
3 different times.. and would not do it again.
i have debated this issue till the cows come home.. there are positives and negatives..
logically it seems that its not a bad thing.. both people are happy, and the wife probably goes home in a better mood and enjoying life more. (that's if she's in a bad marriage).
it also seems to be a decision between only 2 people.. you and her.. so you might think, well its only our business anyway.. and that's probably correct in some way.
2 times, i broke it off but she wanted to continue (and couldn't work out why i wanted to stop!- but they were in bad marriages.. low IL, no time etc.), and 1 time, we both agreed.
on the other hand.. and this is why i won't do it anymore..
If i was married.. even if unhappily, and some guy was seeing my wife, knowing that she was married and goes home to her husband each day, .. i can't see myself holding a good view of him, or showing much mercy if i met him.
I believe what goes around , comes around.. and i just wouldn't like it to happen to me, so i won't do such a thing myself for honour reasons.
There are also practical reasons.. such as the hassle of trying to schedule times to meet, places, and also coming to terms that the other person is leading another life... that can be a drag.
