HELP!!!! Need Advice!!!!

Hey everyone so I need some help. One of my best friends in the whole world who I've known since we were in diapers is pregnant. We are both about to turn 18 and she's about 1m in to her pregnancy. The father of the baby is being a real ass about everything. He originally wanted the baby and now he's telling her to abort it and she won't so he's threatening to walk away from her and the baby. Things have gotten really crazy and I'm trying my best to help her through everything but she's scared to be alone and she doesn't have many people in her life she can count on. I'm worried about her and I need some advice to give her and some advice on how I can maybe help her better. Please keep your negative comments to yourself tho as this is very personal and close to home for me as I had an incident with pregnancy and miscarriage due to strong medication and bad health. I don't want her to go through what I went through and I just want to help so if you please just give me some advice? Thank you!
