Good luck, dude. Wife and I are in the same boat. It sucks being the one with the crazy family, 'cause all you do is wish you could give your child the normal grandparent experience. At least my dad is A+, and left my mother for her bullshit decades ago. Just cut them off; the only person on my side of the family that I talk to is my dad, anymore. Everyone else can go fuck themselves. Life's been pretty stress-free ever since.
