My son does not have any type of relationship with his dad's side of the family. My sons father complains that he is closer to my family and has a relationship with my family but doesn't with his. I pretty much told him that if he wants them to have a relationship that's on him. I have always kept the window open for his family and have always told him sister,mom, and dad that they can call, stop by, or take my son out on multiple occasions. I have done my part trying to make sure he has a relationship with his dad's side of the family. His dad complains and says I do not do my part but I think I do. Do you think I have?
