Visiting my daughter has become a trial for me - I take tranquilisers, psyche myself up for days beforehand and once I get there I don't leave her house, don't go shopping etc, until it's time to go home. In addition to the triggering, I have never met OW and have this ridiculous, terrifying, fear of bumping into her somewhere.
He can't stand the sight of her now and she does not acknowledge him at all. She has claimed to a mutual colleague (who is a friend of the marriage) that my H "ruined her life" by telling a couple of colleagues about the A (at my insistence) and since then she does not even greet him. So I really have no worries there. Thankfully.
If you had "no worries" then you wouldn't be popping tranquilizers and staying inside daughter's house.
A good IC will have you ship-shape and out shopping for grandbaby in not time.
Keep up the forward motion, ItsaClimb.
