I think single dad's are hardworking, they didn't put in much effort in their relationship with their ex wife, lonely, second hand, not as young, wiser, insensitive to emotions, immune to crap. But he's a good man if he takes care of his kids.
I'm sorry, but that seems not only contradictory, but extremely biased.
First of all, hats off to all single full-time fathers out there...some of us single moms know what you are going through.
I have always found single fathers more attractive than single men w/o children. Mainly due to the fact that I was medically advised that I would NEVER carry a child to full term...heh...they got that one wrong...my 8 y/o is proof of that.
Single fathers have given up any freedom they had to care for and raise their child/ren. The ones I have been privileged to meet and get to know are extremely hard working, sensitive to their children's needs, and are actually willing to talk to someone to get to know them first rather than trying to get the perspective mate in the sack first.
So I say, WAY TO GO DADS
