I agree 100% with AAAA! Your mom needs to take care of her problems with your dad without dragging you into it or passing judgement on him! I learned that the hard way. When I divorced my ex, I was always bad mouthing him thinking I was doing my kids a favor by letting them know what a no-good jerk he is. Finally, my daughter told me I had to stop. She said, "He may be an ***-hole but he's MY ***-hole." You might tell your mom the same thing. That's totally not cool of her!

BTW, I think Perna may be right in saying that your dad spread kinda thin. Definetely agree on the jealousy, too! I'd probably feel the same way. It's up to your dad to make time for you, though. There's nothing wrong with telling him so.
