Pax, that is awful. I'm so sorry. I wonder why he still clings to the dog and just doesn't let you have him/her?

I imagine the only thing that makes this easier is that he is obviously deeply troubled and his actions have nothing to do with you. Mine does normal things from time to time so I have to scratch my head and think maybe it's not narcissism or MLC, maybe just an unhappy guy who only sometimes remembers he has kids and really hates his STBX.
