I have been with my 2nd wife for 28 years and have been married for 25 of those years. During this time, I have been the sole provider for my 3 SD's and our son, with the SD's father choosing to be absent and not contribute to his children's upbringing. He would pop in and out of their lives at his leisure and would expect us to drop everything so he could spend time with 'his girls' and never once provided financial support for any of his children. To be honest, I think he was grateful for someone taking them off his hands so he could continue to live a party-style life with no ties.
