You would be well w/in your rights to give him a thorough pummeling if he deserves it. In terms of overstepping boundaries, much like my sitch, I don't think they could be overstepped any more than they already have(W and OM). But I see your point, he definitely shouldn't be in contact w/ dd and under no circumstances should OM ever be permitted to drive another man's ride. He would definitely be looking for a muppet mashing.
I just hope this hell you and I are going thru is over soon. I'm ready to move on w/ my life instead of this limbo. I'm not divorced, I'm not legally separated and I'm still living w/ a woman that is called my W, but doesn't resemble anything other than an irresponsible, inconsiderate, cheating, lying, money-wasting female. It's no wonder I'm not in a hurry to get her back! See all the good my other book has done for me!!? I'm ready to move on!
