15 + Pregnant to Exchange Student?? :(?

what should i do? :[ i'm 15 and a Sophomore in Highschool. i started dating the Japanese exchange student and We have been together about 6 months and became sexual about 3 months ago.Hes my 1st boyfriend and I recently found out im pregnant with our child. I already talked to him and he freaked out! he told me we have to must get an abortion. he said that his culture would never accept a baby out of wedlock and if his parents even found out he had sex before marriage he would be killed. he said in japan if this situation happens even with older couple they always get an abortion, and even married people get abortions too. also he said if he tells the exchange program that he will be sent back to japan before school even ends. ... I dont want an abortion and i dont think he should go back to japan at all under the circumstances!!!!!!!!!!!!!!!!!!!!!! we love each other and he should be around his baby! not back in japan! what can i do ???
