My crush likes another girl ADVICE?

so i was hanging out with my friend "Maya" today and we were talking about who people like. And she was like well I think "Zeke"(my crush) likes "Anna"(my friends BFF and my friend). And "Maya" also said she thinks "Anna" likes him too but they are both too shy to admit it. I know that last year "Zeke" liked "Anna" but I thought he was over her and I asked him who he liked like a month ago and he said no one and I asked "Anna" if she liked "Zeke" cuz "Zeke" liked her before and she was like no. And they never talk! She even admitted it. Also for a while I thought "Zeke" liked me b/c we talk a lot and laugh and the way he acts around me and looks at me just made it seem that way. And at all the parties(bar and bat mitzvahs) he asked me to slow dance first and everytime we slow dance at least once and he never asked "Anna". But my friend "Maya" knows like everything about everyone and doesn't just spread rumors so I trust her. I don't want to be mad at "Anna" b/c she's rily nice and my friend and it's not her fault cuz she doesn't know I like him(we're not close enuf 2 tell each other stuff like that) but I truly am not sure if she likes him or he likes her. and I can't be mad at "Zeke", can I? Anyway sorry this was kinda long. Any HELPFUL and POLITE advice would rily be nice. so, what can I do? thx in advance:)
