Hi L.,
My husband's mother divorced his bio dad (abusive) when he was a year old & married his "Dad" when he was 2. That was the only dad he has ever known. The problem is that his mother didn't tell him about the bio dad until he was 16 years old. My husband did not have any interest in ever contacting his bio dad, but he was very angry that his mother did not tell him about this sooner. She did the same mistake by not telling his 2 sisters (half sisters) about this until they were 16 as well. Both of them were furious. They felt betrayed & that their whole lives were built around lies. I think kids can handle a lot more than what we give them credit for. I would tell them about their bio grandpa, but I would not push a relationship. Let your bio dad work to make a relationship with them. Put the ball in his court & see if he steps up to it. I wouldn't even make a trip with your kids to meet him. Tell your bio dad that you told the kids about him & that if he wants to see them than he can come to you. Your only job is to be honest with your kids & don't stress about the other stuff.
