First of all (if this post is even true) leave his dumb arse. I mean how could anyone be with someone so stupid?
Secondly, I don't know about in canada, but in the u.S now it is considered double homicide if you kill a pregnant woman. I don't know how that works if just the baby is killed. I really dunno. (and I am meaning if he would kick you in the stomach)
so, this is what happens: leave him, file a restraining order, have the child, have him sign away his rights. Simple as 1-2-3
