<human>: Can you summarize the given text in a few sentences?

Hi r/relationships! First time poster so go easy on me if I did something wrong with the format.

I have a bit of a problem, but first a little backstory. Three years ago, I met a girl who we'll call Nicole. We hit it off right away and quickly became best friends, and even went on a couple of (fairly awkward) dates. After a while though we kind of lost interest in each other and started dating other people. We stopped talking for a bit and we started back up again about six months ago. In that time she met her current boyfriend, who we'll call Sam.

Here's the problem though. Recently we have gotten really close again and I think there may be something still there. However, I'm conflicted on how to approach this, because I honestly like Sam a lot and think they are a good match for each other. Now I need some advice on how to proceed. I really want to know if I should try to just stay friends or I need ways to ask her indirectly if she shares my feelings towards her.
<bot>: I have a crush on my best friend and need ways to either stay friends with her or how to indirectly get her to tell me if she feels the same way.
