Boyfriend vs best friend?

So, I'm currently in a really bad situation. I've had my bff for 17 years, since kindergarten. I see her every day, and love her so much. Recently I got a loving boyfriend, and my friend suddenly started acting differently towards me, she even said to our mutual friend that she " doesn't ship us" . Few days ago, she just stoppes talking to me. Without any reason. I asked her what's going on, and if there's a problem that we should talk, and she just said that there isn't any problem, and since then we haven't talked. But, she said to our mutual friend that I am spending too much time with my boyfriend (which is completely not true!) , and she even embarrased my boyfriend while at a pub with her friends, saying that he " stole her friend" , and that I also forgot about her, right in front of him! So, in short, she told EVERYONE about that, but nothing to me. Why doesn't she want to talk to me about that problem? I asked all my friends if that's really true, have I really neglected them, and not any of them think that, they think she's overreacting. I'm really confused about what should I do, because I don't want to get my friend or boyfriend in trouble by confronting her, because she'll knew they blabbed it all to me, but I'm just so hurt that she told everyone that and not to me. So, I stopped talking to her and have no idea what should I do now, should I text her or something? Please help me, is it even worthy of trying to keep the friendship?
