I think if you confront him it will give her more proof that she shouldn’t be with you. I’ve always thought to behave the opposite from what they expect. It makes the spouse wonder where your head is-and if for some reason it doesn’t you won’t be known as that dad that beat up another guy at their kids game.
You and I both know this situation has to run it’s ugly course. Don’t add to it. Keep GAL. I wouldn’t bring up what bothered me at home either. She may be pushing for a confrontation. How disappointing to not let her have one.
IN the beginning after my H was back after three months, I found in our bathroom a hairbrush that was not ours with long blonde strands of hair in it. It was sitting on our counter for me to see. I ignored it. Oh, I was mad but I figured he may have been hoping I would take the bait and start an argument. Eventually the brush disappeared. LOL
I’m just saying vent here talk to a counselor don’t let her get the best of you. You’re better and your son needs that.
