"If I make what YOU'RE doing look crazy, it takes all the focus off me!"
Calling you dozens of time...going to wife's work when her boss isn't there...shoving your kids out of the room.
I'm already scared!
This guy is obsessing/unstable and a danger to your family. Get a restraining order NOW! Your wife may have been lured into the danger zone, but she has no right to drag your girls along with her.
Step 1: Protect your family Step 2: Rally your friends, relatives, & church members to help Step 3: Throw wife a lifeline once this guy's gone
WAW's in the affair fog and can't see the danger this man presents. If he's locked up and she has to go cold turkey, it may be enough to snap her out of it...
