Sometimes it's better to be just friends than nothing, if you have some quality time together. One of my friend was into me back in 9th grade, I wasn't. We stayed friends, we are both in an amazing relationship (not together, make it clear) and we are really good friends. If we wouldnt have been friends we would have miss all the great adventures we had together.
