Born again Christian doesn't want to be friends

Stephanie
I know I'm taking this harder than normal because I'm pregnant, but my best friend has been ignoring me for the past two months and finally sent me a message saying she's found god and doesn't want certain people in her life because of it (a.k.a. Me) My heart hurts so badly right now, and I don't know what to do.  We've always had an amazing and close friendship for the past 6 years, and I feel like I'm losing sister... Any advice would be appreciated...
