My fiancees kids decided a year ago that they no longer wanted me or my kids involved in their lives or the lives of the rest of my fiance's family. They accomplished this by lying about us to everyone involved!!! My fiance spoke to his family and explained that it was a bunch of lies, yet everyone who has cut us off has yet to even attempt to make things right !!! He even got the kids to admit to what they did, and still, no one cares if we are involved or not. He still maintains a relationship with his kids (at my suggestion), although it is distant and permanently changed for the pain and anguish thry have caused. Do I have to invite them to our wedding, which they resent ?
