Friend doesn't like boyfriend

One of my good friends doesn't like my boyfriend. I've been with him for two years now and I love him to bits, and all of my other friends and family really like him.

But this one friend doesn't. It's so awkward when they're around each other. He makes an effort but she's vary wary. Once after a few drinks we fell out over it and I don't feel the same towards her anymore after she keeps putting him down and making digs.

What should I do?
