I like my best mates girlfriend

Basically, whats happened is I’ve got 2 mates that I count as my best mates, and id do anything for em. J.S (one of my 2 best mates) was going through a pretty messy break up, so I tried helping him and his ex-girlfriend, BJD, sort out their shit, to hopefully end up being friends. I didnt really know the chick at the time very well, but after trying effortlessly to get them happy against, I got to know her very well, and she got to know me very well. Then, just to make matters worse, I sorta started liking her. She was what I would love in a girlfriend, but after my mates break up, I wouldve looked like the biggest prick if I randomly came out and said ‘hey, I like her’ so I kept my mouth shut. After about 2 weeks, I got them happy again, so they were actually talking, and BJD and I became really close after it. So maybe a had a chance with her, until, my other best mate, S.S, comes to me and says that he likes her. And then I think again, im going to look like the biggest prick if I said ‘HEY, me too!’. So yeah, as I said, id do anything to make em happy, so, I actually got S.S and BJD together, and now, if they ever like have an arugement or something, she comes to me and tells me everything, but, I feel like a cunt because I comfort her, when I know I like her, and I know my mate would be going through a hard time. What do I do? lol
