What are my rights if boyfriend verbally abused me causing miscarriage?

OMG. 1) get another boyfriend, because this one sounds like a stone loser., and 2) a tremendous percent of first pregnancies result in spontaneous miscarriages for no apparent reason. If this is NOT your first pregnancy with this jerk, then you should be ashamed of yourself, because I can almost guarantee that he was an idiot previously, and you cannot expect him to grow up by your getting pregnant. Take this as an educational experience, and do NOT let him impregnate you again, and I strongly recommend that you look for a MAN to be your life's partner instead of a BOY. I told both of my daughters that they would have to kiss a lot of toads before they found their prince.

To see a lawyer to determine if you might have a legal action and to leave him for you own protection.
