What should I do, my best friend doesn't talk to me anymore?

(The star represents my best friend) My best friend* doesn’t talk to me anymore, because I made fun of her* boyfriend, because he got a tattoo. He’s 17 and he got a tattoo, of course I had my own opinion. But ever since that she* hasn’t called me, asked me to see her*, nothing. I try talking to her*, but she doesn’t put any ounce of effort into the conversation. So I talked to one of my other friends about it, because my grandfathers dying, and I’d like her and my best friend* to come to the wake with me. So my other friend told her*, and she said that she* didn’t know what to say about the situation. I mean its been 2 weeks, and I’ve tried talking to my best friend*, but she’s* just treating me like complete, and utter trash. Because I made fun of a tattoo. Should I try talking to my best friend*? Or should I just move on with my life? Because apparently she doesn’t care anymore, and it’s starting to lead me into a very depressed state. I miss my best friend. Please help me with this dilemma.. thank you very much for the help!
