My ex was a successful, wealthy, controlling, businessman. He had a nasty divorce and custody battle over his 2 kids, years before I came into the picture, and unbeknownst to me till I was knee deep...
He wanted sole custody because, he told me, he wasn't going to give her one penny, if he could help it, even though he could easily afford it. He loved money and control and hated her. He got full custody after driving her into the ground, but he left those kids on their own or with a girlfriend to raise...it was all about control and money, for him, imo. He won...that's what mattered, too, imo.
ETA: AND he was a hockey coach, big in the community, seen as a wonderful Dad...I know different...I was there, on the inside.
SO...I'm not buying the devoted Dad deal, yet...although, I feel that's really not for me to judge...devoted Dads kill too, imo...
