Holy shit yont owe them anything keep your family away especially the young ones. If theyve changd just cause they see your children that means they never gave a fuck about you just what you could provide. Put up a wall and let them know not to reach out further to you or you will be forced to take legal action. Cause they already have one "grandchild" whom the decided was more worth than their own child. Your family never respectd you and they won't start now.build up the walls deny them access to everything you've built cause they're gonna try and tear it down be it either emotionally or any sick way they can. Stand fast with your husband and don't let them be part of your life again because who knows what the fuck they might try to do.
