Little back story

I've been great friends with this girl for ten years off and on. We were close for 3, took a five year break, and the last two years have been best friends. She is a lot like me in a few ways, but also very different. She is married, but cheats and hates her husband. She has no real direction or goals yet mocks mine. Her morals and values don't line up with mine at all, but we have similar interests.

I'm 14 weeks pregnant currently and she was the first one I told at 3 weeks. She was super supportive and happy at first but changed. She doesn't like my boyfriend and has decided to voice that online by posting things on Facebook indirectly about bad boyfriends. She also said I should have an abortion at one point cuz I'm going to ruin my life.

She has not even once showed love or support about my choice to have this baby. She now is not speaking to me...a week goes between texts and she only answers if I double text (send one Monday, send another Thursday). We last spoke over two weeks ago. The last conversation was about my baby shower...which she said was stupid because I want to have it in November not December (I'm due in January),

My question is does anyone have hints or ideas how I can end our friendship without too much drama. She scares me honestly because she is vindictive and petty. I worry she will try to ruin my relationship.
