Secret crush

I have a crush on my friend and he is bisexuality but mostly likes guys. But he's been acting really close and touchy with me and I suspect he might like me but my other friend who is gay likes him and always tells me and I feel guilty as I like the person he likes, but my crush acts more touchy and kind to me, flirting slightly but In a joking g way. I dont wanna ruin my friend ship between. My friend and crush, I know my friend would hate me if I dated his crush, even if his crush liked me first. I just feel so guilty and upset about it because I love my friend but also my crush and if he asked me out I would say yes but my friend liking him is not helping me.. if u have any advice or same storys please let me know..🙁
