In my single days I always shyed away from women with kids. Now that I am hooked up - I would consider a F*ck buddy with kids, as long as she is not looking for any commitment, because I can't give her one.
I don't understand, why is it so wrong for a single mom to expect her partner to support her child? Doesn't any woman expect that for their future child? A single mom can't help it that she already has a child.
