He had a choice - don't take anyone's word for anything and USE A CONDOM. Yes, just like any other form of birth control - except abstaining - there is always a risk of a pregnancy for both sides.
Just because you told her you weren't ready to be a father - you seem to think that makes you immune from any consequences. What kind of thought process is that? Maybe she was just as surprised as you when she came up pregnant. You seem hell bent on "you have a right to play, but nothing should happen you don't want to happen?" What world do you live in?
It's a gamble no matter who you are - have sex, have a chance of getting pregnant. You played the game, now pay the price. Nothing in this world comes without a price. You were not responsible in your actions - no condom - so now be a big boy and pay the price. If you always take someone else's word that Nothing can happen, then you are positively naive or downright dumb - take control of your own life and actions - wear a condom.
With your attitude you are doing this child a huge favor by staying out of its life. You say you want children some day on your own time schedule and on your own terms - I feel sorry for that child you have then - what if he or she doesn't live up to your expectations? What "defense" will you use then? What responsibility will you take then? What if the child you do choose to have is not as smart, as atheletic, not as good-looking, or whatever else you can dream up - as you expected it to be? Whose "fault" is it going to be then? The genes from the mother? How will you handle that? I can't bear to think of what you will eventually put a child through down the road.
I wonder also if you realize how whiny, irresponsible, and down right immature you sounded on the show? I wonder how your parents feel right now seeing you and knowing they have a beautiful grandchild out there who you want to deny? I hope they at least do the right thing and know this child, if they have a better attitude than you do.
I wonder what you do for a living? I wonder how you will handle the business world in the years to come when life doesn't always play "fair" with you? My guess is "not well".
The man who appeared with you did you no credit at all. Not your lawyer - the other one. He seemed very combative, egotisical and not well informed. You did yourself and your cause no good at all on the show today. My guess is that more people laughed at you and your supporter than listened, much less sympathized. Grow up.
