Well thanks everyone. I know you want me to feel better and much of what you say is true. I still feel like I should examine why he likes it better at Dads house (he told him that over the phone unprovoked by my AH, I was right there) and he's not being mean or manipulative. The other son would consider it, but this one is just speaking his mind.
Regardless, I appreciate your kind words and input. Last month he liked it here better, and yes, he's a kid. I attach all this other crap to it..
