Brick wall ex

So me and my new boyfriend have been dating for a while not to long but we have hanging out non stop and things have been amazing he treats me like gold and he even stopped being friends with his crazy ass exs but they started acting crazy when we started dating and one of them is a psycho and kept calling non stop a while ago and was harassing him talking about its her or me and I don't want to be friends with you anymore if your gonna date her and he was like "ok bye lol" and even hacking his Facebook saying crazy things and changing his name to rude things but she contacted him again through email and was saying I need your opinion and we have to talk in person I have something to tell you and I was made cause we were having a great time together n we were hoping that it wouldn't be the new we were dreading and it was she was pregnant but i have s gut feeling the it's not his and she is just trying to break us up and now he's confused and mad and his dad was never there for him so he might want to stick up for this child unless it's his cause he was played before into thinking his last ex was pregnant sorry for the random info I'm just so scared and angry its like she doesn't want him to be happy and my family and his family already love both of us compared to our old exs 😡😖💔😤
