<human>: Can you succinctly summarize the text in 1-3 sentences?

Hey guys. . I just turned 17 a little over a month ago, and I have recently developed feelings for a girl . . who is 14. I haven't really talked to her much & another thing I forgot to mention is she is in 8th grade and i'm a senior.

I have run into a problem where I can't stop thinking about her or at least the "thought of her" I suppose. I really just want to be friends for awhile, considering the grade difference & college soon, but I feel as though my "feelings" are holding me back from even becoming friends. Don't get me wrong, I'm not looking to have sex or anything, I just really like her personality and she is really good looking. 

I guess I really have two questions, the first being is that: is it natural for me to have these sort of feelings. . being sort of "obsessed" with the "thought" of someone? Is it just relational immaturity? Or is it a sign of a much deeper problem? The second question is, should I pursue a relationship with her of any kind, and if not. . how do I rid myself of these feelings that overcome me whenever I see her?

In context, I have had a girlfriend before and am not antisocial or anything (if that matters) and honestly I don't feel 3 years is a large age gap, but rather the grade difference (8th and 12th) could be a huge problem in the future (if I was to pursue a relationship.) But it's consuming my thoughts and such, and not sure where to take it. . so I took it to reddit :D
<bot>: Really obsessed with the thought of this girl, and haven't established a relationship with her yet. Wondering if it's normal & what I should do about it.
