What SHOULD I do?

I'm pregnent for about 5months and no one knows about it... Mom, sis and aunts were wondering why my tummy so big... But all i can say is just only i'm getting fatter and the fat only grow at my tummy... No one knows the truth... As usual we only contact by text messaging... As we were talking about abortion... We started to argue... I really dont know what should I do... Should I go for abortion???? My head keep on thinking all sorts of things... What am I doing? Did I ever did something right? Will he keep on his promises? Does he really remember what he promised? If he does remember why all these keep on happened over and over again?
