I agree with luna, it is very nice to see a single dad take on the responsibilty. In fact, I question a mans character, if he is not involved with his kids. And when you start dating, you will have a good understanding of the ups and downs of singleparenthood. Many men who date single moms, dont understand the bond that parents have with thier kids. Chances are you are going to meet a single mom yourself and you can go into the relationship with eyes wide open.
In a nutshell, thank God, you were able to step in and take care of your children. Kids need thier dad to just as much as they need thier mother.
take care
