Is my friend a !!! Please help!!?

So I have this friend who I has been my bff for about a year. Right now I am dating somebody (let's call him mike) and I am a . He is like a brother to me but I still go out with him to shake off all the gay rumors. Anyway, my bff I think is in love with him. They used to like each other but were too lazy to actully go out. Then he started having feelings for me. My bff (aka Mary) is always jelous of us and always talks about him being hot and that we should break up because they were supposed to be happy together. It really bugs me but I know that's how it is supposed to be. So lately she has been like holding my hand and snuggling with me and like kissing me. And she is always like if mike wasn't here I would kiss u right now into my ear. When she holds me I try to avoid the burning sensation in between my legs. But I know that my boyfirned hates when I act gay. And idk if she is trying to break me and mike up or if she is just being "friendly" and yes half the school thinks i am gay with her(and yes I sort of wish I was after being rejected by my othe bff). I am in 9th grade! Best answer gets 10 points, go nuts. Btw: today she ed me a squezzed my . She was also like "I love you". (lol! Oor pricipal is really suspisous she will follow us around to make sure we dont grind on eachothere) She says she isn't gay...
