Need to get more up to speed on WM's current situation. But if I were you WM. I would demand a paternity test from her and watch for a reaction. Trust their actions not their words. Put up some boundaries and rules on the relationship until further notice. Your rules. No co habitation until further notice. You got some big red flags of a chameleon and a potential NARC there buddy. Sounds like you fell for the ol bait and switch again and she is already giving you ultimatums. Don't let her emotionally manipulate you. Use logic and reason.
