MIL and baby.

We aren't married just yet, but very soon. So I call him my husband anyways. My soon to be mother in law.. For the past two years she has been horrible. I have had multiple miscarriages. She has said she hoped the babies died, that I was lying and wasn't pregnant, that I cant be a mother, all the way to she wont be in its life until I get a DNA test and prove its her sons. Then, she would say I don't deserve him, that i'm manipulative, etc. She has called me every name in the book, threatened me, so has her husband. They both have been just absolutely horrible and it put me into depression because after losing each pregnancy, I felt horrible and alone because of those things she would say each time she saw me. Then before my fiance left for training, I found out I was pregnant. She knew and she continued to say bad things. I'm now 6 months and haven't talked to her. I guess from what he says, she's really excited and wants to be there and buy things for the baby, etc.
