My H only had a friendship with OW as well. Now they live together. They were more than friends all the time.........I'm not saying it is a PA but it is probably an EA. Sorry.

I also wanted to believe my H was different and told the truth and would never cheat on me. Got a bit suspicious when I asked H whether he had kissed her and he said yes. Couldn't get my head around how many of my friends I had kissed on the lips!

Many MLCers have affairs as part of the course. She is just a symptom no more and no less.
