feeling depressed and pissed

Feeling alone and hurt. My husbands mother, who was once my closest friend, back stabbed me and totally disrespected me. Ever since she found out I was pregnant she's been telling my husband that I should get an abortion and that I'm trying to trap him and that she wants him to get a DNA test when the baby is born. I feel so disgusted and angered by her. I was always there for her and trusted her more than my mother on some things. My husband isn't effected by it he knows his mother is crazy for saying what she's saying. But he still thinks he can fix his mothers and I relationship. But I've totally lost all respect for her. He wants her to live with us when he gets his new duty station but I hate to say this because I love my husband but I will not live in the same house with her. I hate putting him in a situation as to he chooses me his child or his mother. I just don't feel comfortable. I'm letting god handle the situation but it bothers me every day all day.
