My dear, u re just dumb. First abortion didnt make you realize that he is just using you. if you like expose him, you are still gonna loose, cos you are on the losing end cos you are a woman. IF you expose him, he already got children; but how about you. maybe you were blessed with those you ve aborted. All i will advise is that you become a nun. Good luck finding the unlucky man to carry the burden.
