well I am a father not a dad A dad is some one that is there raising their kids a father is a man that is around sometimes I love my son very much and in my case it is different but in yours well I think that he shouldn't forget those are his kids and don't push him away or force him and when the kids get older and ask about there father talk good about the butt cause it will all come out in the end the kids look up to you and need you raise your head smile and be proud of those 3 kids cause they will be there the rest of your life now take the kids for ice cream and give them a hug
