My closest friend of 15 years just moved in with me to escape her sociopathic (now EX) boyfriend. He is verbally and emotionally abusive, controlling, obsessive, and in denial that he ever did anything wrong.
A week after she moved in, we discovered she is pregnant.
Long story short, she is leaning towards keeping the baby (6 weeks along now) and decided to tell him since "it's half his kid".
She has explained to him that if they had the baby, she would not keep it from him, but they are not getting back together.
He keeps texting and calling and saying he wants her to move back in, and if she doesn't, she should just abort it.
Last night, he called her saying he is going to hurt himself and he wants to "get together and talk this out in person".

How do I get her to stand up to him!?
