<human>: Can you condense the text into three sentences or less?

I have a crush on a friend of mine, J, who is clearly only interested in dating S. But S has no intention of dating anyone until she's 24 and she doesn't seem to be interested in him that much anyway. I didn't know this until recently and didn't pursue him because I always assumed that they would end up dating.

Meanwhile, I had been consulting a mutual friend of all of ours A for advice about my bisexuality (he's bi as well). So A and I have been consulting each other about our lives, him about his ex's. We've grown very close and he confessed to liking me but I declined and gave him some time. Problem is, J and A are very close friends and I don't want to make things more complicated than it is. Should I wait before telling him that I like him? Would it be better to just not say anything for the sake of our friendships?
<bot>: A likes me, I like J, J likes S but S doesn't like J. I don't like A. A and J are close friends. What do?
