I don't get why a successful businessman would need help dealing with a pregnant girlfriend.
Either she has it or she doesn't.
If she doesn't have it, you pay for the procedure.
If she does have it and you stay together, you pay to support the kid.
If she does have it and you don't stay together, you pay to support the kid.
Those are the three outcomes, and if you have any means, none of them should be especially frightening.
