Abortions can significantly reduce the possibility of a healthy pregnancy later on in life. So unless she's really stupid she'd just keep that one and say that she is ready for a baby and that the OP can either be now or later. Or she might be opposed to abortion and various other reasons that would cause that plan to fail.

And what exactly are his other options? 1) Stay with the cheating wh*re, support her through her pregnancy, then find out the child is not his. 2) If he is the father, have a relationship with a woman he no longer trusts or likes. Such a relationship is bound to fail within 2-3 years. 3) Leave her now, find out the child is his later, and as above get stuck with child support for a child he never wanted.

I think it's upto the girl to decide if she wants an abortion or not, not him. If she wants to keep it then I think he should find out if it's his, if it is he pays child support or at least comes to an agreement about how much of a father figure he needs to be with the girl (and get that well documented or something), if it isn't his it's not his problem. But obviously I'm totally wrong and the best solution is for her to get an abortion, and it seems clear that she wants kids, so you know, obviously the right thing to do is to pressure her into getting one. (yes, that last bit was sarcastic)

So basically you believe that only women have the right make a decision, and men have men have to bear the consequences. You're a typical misandrist bigot. The only reason the situation has occurred is because she cheated on him. Why should he have to take responsibility for her deceitful unethical behaviour? Of course she's too self centred, which is why subterfuge is required to make her do the right thing.

Actually I agree with your second paragraph. (Not sarcasm.)

No I don't believe only women have the right to make the decision. Personally I think couples should talk about having kids before they have them, but if the girl does get pregnant they should then sit down and discuss it again, if they both think that an abortion would be best, then fair enough. What I disagree with is the pressuring into getting an abortion. He doesn't have to take responsibility for her being a cheating ***** (though technically the fml never mentions she cheated, for all we know she was raped, it's just the less likely of the two options), he can chose to leave her and tell her to phone him when she's had the DNA test to let him know if it's his and to show him the results. He doesn't have to stay with her to be a father figure. If she wants the baby and he doesn't (and it's not his) then she has to deal with the responsibility of getting knocked up by someone else. Not him.
