What kind of woman dates a man who knowingly abandons his (child)ren because he didn't want them with the other person he knocked up while dating a former partner? (To keep the conversation interesting, let's say he was with his former partner AND wanted kids..Then changed his mind once the deed was done, which apparently is commonplace...)

(I'd ask this from a gender neutral standpoint, but women are left making the ultimate decision(s) and sacrifice(s) irrespective of what the male wants in this situation.)

Is it the norm now to completely haul off when faced with "the consequences"? Do men normally regret this later in life? Anyone here ever been in this situation or been the man to leave?

I read in the news all the time of women taking off and abandoning their children, too. I'd really like to hear about their counter parts behavior however..
