I'm friends with a gay woman. Am I going to hell?

Hi, I'm a girl and one of my best friends recently came out as gay. Since we live in a small town, almost everybody knows. The local pastor told me to stop being friends with her because "homosexuality is contagious and she'll infect me with her lesbian germs." He also said if I remained friends with her I would go to hell for being in cahoots with a lesbian.
