<human>: Could you distill the essence of the text into 1-3 sentences?

As read above I'm a 19 year old male and I am struggling with moving on from this amazing girl. Some background information, I've known her for two years almost now. We worked together back when we were 17 years old. If you look at this [post] you can get a lot more information about how we meet and got to this point. Rather then spacing myself from Molly after telling her how I felt, we got even closer. We both got to a point where we consider each other our best friends and I am so lost.

We agreed we couldn't do anything that would hurt Ava, but it ended up hurting me even more now because the two of us don't want to seperate. But Molly doesn't want to hurt Ava. To make matters worse, Molly is not emotionally available to anyone right now. Molly says she doesn't know what she wants right now, and that she doesn't know what to do either. Which is understandable to me as I am in the exact same boat, but Molly loves to go out partying and will hook-up with random guys. I know I'm wasting my time on someone who could never feel the way I do. I don't want to lose her, but at the same time I know it isn't healthy for me to pine over her forever. I don't know what to do. I don't want to just leave Molly because I know somewhere deep down she has seen the same feelings. I don't think I'll be able to make these feelings go away anytime soon, so I'm basically lost. I feel like I either need to ask Molly to just tell me it won't happen and we seperate or we stay friends and I try to move on the best I can.
