What to do when you keep accidently end up liking men who like your bestfriend?

My best friend and I are really alike, and that can be good but it can also be bad when we end up liking the same guys. The other night at a party I ended up kissing the guy she liked because hey...I saw him first right? and to be fair, he kissed me first. I lied about it after because I felt bad (yes alcohol was involved). I told her I left the party shortly after her. This guy said he would call me, but he never did and ended up texting her even though he said he would call me and he seemed to have no feelings for my friend. I know a loser when I see one, so I stayed away from him after that. However, the other day I ended up meeting a guy she had gone one one date with and had no interest in. He ended up doing a big favour for me, and I thought he was really cute, but of course the day after he ended up texting my friend and they are going to go on another date! I don't know what it is, maybe it's my luck or what but I don't know what to do. I keep meeting guys and she keeps taking them, even if she doesn't do it on purpose. She likes another guy that she goes to school with anyways, and I worry that she might be stringing along this guy that I have quite the crush on and I'm not really sure what to do about it? I don't want to take away happiness from her, but quite frankly all this secret keeping and lying about my feelings is making me miserable. Help!?
