That is a very truthful saying, in most cases ( i tell you that as a man) things get harder as we grow older, and you (people) have children, in our (men) case I think we are afraid of commitment by nature, and we disguise that by calling ourselves "players" because we don't dare to cross the line. ( no offense to all my playas in da house ). I tried to cross that line not too long ago, but it did not work out... well that's life in the big city. Personally i prefer a woman with no children because i 'know' what is Numero Uno for her, and is not me(men), Children will ALWAYS come first for a mother.
I am not trying to say that because women have children they have no chance... that is wrong, the race might get a little hard, but you are still in it.
One of my best friends has 2 kids, and I like her alot, and she likes me alot too, but we have different plans... if you ask me... would I give her a shot (for real, not just a brief relationship) knowing that she has 2 kids?... the answer is YES... not because of her only, because her 2 kids love me alot and i love them too.. and yes, I agree with you that kids need a father figure, and women need love too. I notice every time I go to visit her, we seem like a family, and I enjoy it, and I can sense the need on those kids for a male to look up to and talk and watch Sponge Bob with.
As of me, I have also (in many cases) the need to care for someone, not just get my freak on. LOL
