I've heard there was a general preconception regarding the fact that single fathers have more time on their hands. I've talked to people who actually said that a friend of mine must have plenty of time to spend with his children because he's a single father.
Do you really think that not being involved in a relationship implies that you and your children can spend more time together?
Honestly, it depends on the characteristics of the father. What they want to do or feel they need to do.
As a mom, I have a list of things that need to be done during the day; I'd imagne a single father has to accomplish the same tasks. It's not easy to get everything done in a day if you are a stay at home parent or a full time parent.
My fiance spent more time with his young son AFTER I met him because I demanded it. It was easier to take him knowing his partner wanted him then worrying about what I would think. I laid it out for him, if those pictures on the wall were of his son (looked to be about 4) he needed to be in the house with us part time because I would not have a child in the family that wasn't "in" the family. (Turned out his son was really 9...)
My girlfriend and her boyfriend have his son more too now that she is in the picture. He feels better equipped to handle the child with the extra support. He grew up with only his mother, so he was terrified to be a single father.
On the other hand, we have a friend who has fought tooth and nail in court to get his daughter. She is his world. He spends every waking moment with her and spoils her rotten. Finding a partner, while he admits it would be nice, is the farthest thing from his mind. He would prefer to come home and build a trusting relationship with the one girl who will, hopefully, never break his heart.
Speaking for the system, single father's are under a lot of direct and heavy fire from government organizations to be doing the right thing. Programs, work, school, it all takes time away from the child. The support order reviews and meeting with case workers take up a good portion of time...not to mention the million phone calls some dads have to make each day to fight to keep their children.
