Well well well...
OP... you fukked up by allowing nikkas on the Coli to rile you up and bring their advice into your home. You bout to fukk around and have to move in with one of these nikkas after they done helped you fukk your marriage up. Don't you know the Locker Room is fulla pimps who would never marry nor trust a woman, hate children, and don't believe in anything except gettin' p*ssy no matter what consequence comes with it? You shoulda known better, bruh.
But I can't even blame them. I believe you and your wife got a good marriage goin'. I believe that this girl is just that fukked-up friend that you still got love for even tho' she does dumb shyt. But the lines should be drawn on it... not the way you ran up in the house and did it, but definitely in a rational way. On one hand, she's gonna look at you all fukked up cause y'all been friends for so long and she won't understand why you'd want her to move out. But she's dumb anyway, so it ain't SUPPOSED to make sense to her. If it's somethin' you can't deal with and it's to a point where you're just disgusted with the whole situation, you gotta put your foot down to a point where she knows you ain't shyttin' on her, but this living situation ain't gonna work out. It's a lot easier to do than you're makin' it out to be.
And to a degree... you kinda gotta look at the shyt realistically. No chick that you AND your wife fukked before is gonna think that walking around in her underwear is gonna make you uncomfortable. Y'all are all best friends and even MORE than best friends, so why you think she'd believe there was some kinda limit is beyond me.
