well, i suppose all have chided you about your irresponsibility,
and i will do likewise. it is indeed unethical for your girlfriend
to abort the child, especially so when she doen't want to bring
shame to her family. she should face the consequences of her
actions. if say, she had health problems, then abortion is
inevitable. if you can't support the child, there's always adoption
agencies. who are we to play God and dispense life or death? do you
think abortion simplifies things... if your girlfriend thinks so,
i'd gathered that she is a pretty shallow person. there'll be
grief, and also from there henceforth, you will look at each other
in a different perspective.
in any ways, the decision is ultimately up to you guys, and i do
sincerely hope you do what is right.
