I could probably tell you both the good and bad of seeing her.
I met with OW at my request. I didn't want to "run into her" in town and have not already said my peace. I also was curious what was so special. WH had introduced us a month or so before DDay, but I wasn't exactly paying attention at that point.
In my case, she was beautiful, but so broken. I could see how broken she was. At the time of the meeting she was still very much in love with my WH, but he had been very clear for weeks that his feelings were gone/done, it was over, and that she needed to make it work with her BS. I didn't get what I wanted from the meeting, buy I was still glad I did it.
So, the good-
-she confirmed to me that WH had clearly told her I was his priority and that he would have nothing more to do with her.
-I got to see her and get the imaginery wild images out of my head.
-I got to see her brokenness
-I got to hand deliver a letter to her
-WH was very disappointed with how she handled things and treated me...this helped with the emotional break for him
-WH got to see JUST how strong I am
-This made OW very uncomfortable
The bad-
-I didn't get the closure I wanted
-I didn't get the apology I deserved
-I now have real, not imaginary images in my head
-After the meeting, my anger turned from her to WH...no more unknown person to place all my anger on
-Well, although it is fairly uncommon for APs, she is beautiful AND thin...older than both WH and me but aged very well.
Only you can make the right decision for you. Take your time. I wish you the best.
