parents... ugh - help?

my parents came to visit on saturday. made a big deal about how they barely slept the night before and got up super early to come. they took the kids to a beach 2 hours away because it's known for shells and shark teeth. and made a huge deal about the trip and stuff. but we live like 10 minutes from the beach - they didnt HAVE to do that. and again - a huge show about buying them things and giving them money. and a big deal about moving to the mountains and making a cool place for the kids to come visit.... it's so all about them... but these are the same people who turned their backs on my abuse. my mother, when it was happening and my stepfather when i finally told and reached out for help. they refused to believe me. to protect me. to offer even a hug or a tear for what i went through. a care at all. i am at a place where i can no longer trust them. finally the anger is coming through and i dont need them in my face playing "hero" when they were the villians. i am trying to walk in forgiveness and i know that God says i need to honor my parents... but here's the deal. i dont believe honor equals stupidity or that forgiveness equals allowing it to happen to my children. i've been confronted and it's suggested i need to cut ties... or at least to establish healthy boundaries. guess i just need some input and support. help?
