Jealous friend

I started seeing my new boyfriend. And my best friend doesnt like him! And obviously ive been spending alot of tine with my new boyfriend and ive been busy at college and with my own kids! I do try and put an effort in with her and offer to met up for lunch and for a night out! Shes been really unsupportive towards me and my partner. She hates him and when we used to go out together and if my boyfriend was out she would make silly comments about his appearance and about how im whipped and today shes writting silly immature statuses about me on Facebook! I don't see that shes being supportive or being much off a friend cause a reel friend would be happy that ive found someone I wanna be with?
