<human>: Can you condense the text into three sentences or less?

So I've recently realised that I like her a lot, even though we've never been on a date or anything - just texted and been together with groups of friends. 

I've liked people in the past but to nowhere near this extent, and I'm fairly sure some people would call this feeling love. The problem I'm having is that she's way out of my league and I'm about 90% certain that she doesn't feel for me in a romantic way at all. 

I smile like a moron every time I think about her, text her, or even just see that she's responded to me. Just messaging her a few times a day has made me ridiculously happy.

My problem is that if (probably better to put 'when' in all honesty) it ends up being at a point where a relationship with her is completely out of the picture, I'll be destroyed emotionally. I've tried to tell myself how unlikely it is to work out, and although I admit this - I'm not sure I actually believe myself.

I'm just really confused at the moment, and all I know is that I'd do almost anything to get into a relationship with her - but I don't see it happening.

How do I prevent myself being so upset if all these smiles that I'm having just... stop?
<bot>: I've found someone I 'love', but I want to try and prevent myself from being really sad if it doesn't work out. Any advice?
