The hardest thing I had to deal with in my current relationship is the tension between my husband and my children's dad. He was a dead beat, and my husband stepped in and raised my children. The other guy had always tried to hurt the relationship between the kids and their step dad, which made the two men not get along. I wish he would have just left the kids alone and let my husband do the things that he could have, should have, and would not ever have done for the kids. Instead, he tried to become their friend (after they were grown) to get them away form their step dad, succeeded, but then started to treat them like crap, so you know what happened. They came back to their step dad and disowned their biological one and its been that way for 2 years now. They finally seen that the grass was not green on the other side as they thought it was when they were growing up. We tried to keep them from the hurt we knew he would cause them but they had to see for themselves and now they regret giving him a second chance. Their step dad did not get mad at his now adult children, but told them to keep moving forward with life and relationships. Don't back step to something that was bad for you.
