So there are three sides to every story, and of course, we are only getting one of those from the OP.
Although I would go to the ends of the earth for my boys, I understand that not everyone feels the same about their pets. There are some circumstances where people do need to rehome their dogs, I get that. (Although I don't really agree that this is one of those circumstances). I'm all for helping people do this the best possible way - but only if they WANT help.
It was the flippancy that p*ssed me off with this post. Okay, yeah - it's text, but I couldn't read any real regret in what the OP posted. It was basically "The wife wants her gone - enough said". Like he was deciding what to have for lunch, or something. He also didn't mention her name. That made me sad.
He said that he has already moved back in with the Ex. One has to wonder where this little girl has been in the meantime?
