The frustration felt by both parties is understandable. Afterall, you did not plan to have any children at this age. Either decision made, there' may be one seriously upset party.
Apparently, abortion would leave a deep scar on the girl's life and may also adversely affect her health. If you see her as your future life partner, would you bear to hurt her health?
On the other hand, forced responsibility may result in an unhappy family, unless your mindset is changed -- i.e. accept the responsibility whole-heartedly and work hard to support your new-found family. If you calm down and decide to take up the responsibility like a mature man, I'm sure you can look forward to a blissful life.
Since your parents may not provide you with patient listening ears, how about going for a counselling session with 1 of the many family service centres in Singapore? I volunteer with such an organisation, so am confident that they can provide you with professional help and link you to people who are experienced in handling such situations. (Obviously, no one in your family has faced such an issue before, so an expert in this field could give you much more reliable advice based on a wide range of perspectives.) The sessions are either free or very affordable, depending on your family income.
Your feelings are as important as your girlfriend's, so in order to ensure that both of you make the right decision and fully understand the rationale behind the decision, do try out counselling services.
