<human>: I'm sure you guys have seen this a lot but I'm not really sure what to do and I REALLY don't want to mess up my relationship with this guy. 

So, my best male friend for years now (I think like 8 years) and I have always had a bit of a mixed relationship. He has wanted more with me on and off but I have always been hesitant. I really value our friendship and don't want to mess it up if/when we break it off, and also I have never had a real relationship and I don't want my first to go badly, especially with someone I already care about so much. I do want more with him, I'm just not sure how much more or in what level of commitment. 

He has told one of our close mutual friends that he really does want something more with me but that he doesn't want to make a move unless he is sure I feel the same way.

Could you distill the essence of the text into 1-3 sentences?
