STBXW and I split in February. I've moved out and started a new life but a couple of days ago during pickup of kiddos she off-handedly mentioned how a "super hot" bartender tried to take her home. I can't stop thinking about it. I'm filled with jealousy and compulsion to figure out who this dude is. I know she doesn't belong to me anymore, I know she is free to do as she pleases, but these husband instincts still exist from years of being together exclusively and I'm just constantly ruminating about how some dude tried to fuck my ex wife.

Guys who have faced these unwanted and lingering feelings of jealousy, please tell me what helps (besides time and therapy, I'm doing both).
