It's complicated... but what isn't?

I had two friends, Kyle whom I have known since I graduated college and Sara who I was closer with, but have only knew for a shorter period of time. I considered her my family and she felt the same way. I introduced both of them and they hit it off, I was adamant at first because I didn't want to get caught in the middle of anything and I had the understanding that their relationship has nothing to do with me, but it wasn't that way. Instead, I became the problem. Kyle declared his suspicions about my intentions with Sara, I tried to be clear that there was nothing between us and our relationship was strictly platonic, but he was convinced there was something going on. Sara played the peace maker and tried to resolve both our differences and things would be good for awhile, but one day Sara told me wasn't even allowed to even be around me. I went to meet with Kyle and talk to him about how or even why would have these thoughts, but he was never direct or had an explanation for how he felt and was simply convinced I was after her. So I moved on and left the two alone because this high school drama was beyond me. It saddened me for a while to lose contact with such a great friend, but now I am at peace and happy for them both. I simply wanted an unbiased opinion on the entire situation, to know if I was in the wrong or not?
