I don't allow anyone in my home that I see as being toxic for me. My daughter's BF is a raging codie and that's her problem to deal with, one to one. He's made a few codie slips while in my home, and that's my problem to deal with. He's not allowed here but maybe 1-2 times a month now, for a couple of hours and no overnights, no closed doors. This was after a few months hiatus. I took this up with him, not through her, because it's my home and my boundary. He's very aware my door may shut on him at any moment. I didn't tell him how to stop effing up, I only told him it had to. So far, so good.
