<human>: I am a 19 year old male who is interested in a female junior (17 years old) at the same high school that I graduated from. I have had a crush on her since my senior year and her freshman year but at the time I was hesitant to speak to her because high schoolers tend to get all up in your business. 

We first met in study hall my senior year and I talked to her for a bit. I am so happy I did because I got a taste of her amazing presence. The next time I came in contact with her was at homecoming and I did what every high schooler would do. I walked up to her and we started to grind. It was hot but I feel like it might have been the wrong move. I just wanted to reach out to her but I couldn't think of anything better at the moment. 

Ever since I was afraid to talk to her because I didn't know how to follow up. I don't want sex, I am not that type of person. I actually wanted to form a relationship with her. But since all I did was grind her, I found myself in a ditch and I didn't know how to get out of it so I played it safe and just stopped talking to her. 

I spoke to her on Facebook the summer of that year just to see how she is doing, not trying to push anything. 

Now, I am a sophomore in college and she is a junior in high school and I am a volunteer coach for the volleyball team for my high school and I see her all the time. I always smile and look at her genuinely. 

I feel that we could have such a strong connection and I would like to give myself a chance to try but when it comes to these things I think too much, so I am asking for your advice on how I can approach this situation.
