Do I have any right to be mad?

Okay so recently my guy friend of only like 3 months texted me telling me he liked me it was super awkward for me because I don’t like him at ALL. And my Best friend knew for around 2 weeks as well as some of our other “friends” She knew I didn’t like him I made it very clear. But she still put me in a very awkward situation we have been friend for 6 years so she knows a lot about I feel. And when I asked her why she didn’t tell me and when I asked if there was anything going on with him and if it had to fo with me she lied and made up a story. Also when all of us have lunch together she’s very different and points out my flaws all the time things she knows I don’t like being pointed out. We are only juniors so I know this sounds like some high school shit but I’m just kinda bummed shes being rude and making fun of me as well as straight up lying to me.
