<human>: Can you summarize the given text in a few sentences?

So I've known this guy for almost half a year now, and I've gotten very attached to him in the meantime. I've had a few crushes before - none of which I've pursued, and have consequently gotten over without a hitch - but this one seems to be seared into my brain.

The issues are myriad with actually attempting pursuit, however. First of all, we met online through Steam, which means we've never actually met. (Though we're planning to in a year and a half or so. Of course, that could fall through.). We do talk and text a lot, and hang out and play games, etc. Beyond that, We both have zero interest in an LDRs, and I'm quite consumed by college and everything else in life. The third issue is, of course, the age. I want to believe I'm 'mature for my age', but really, I have shit to learn. This dude, as fantastic as he is, has eight years of life experience on me. Where I'm hitting my early twenties, he'll begin hitting his early thirties. (I am also sure for that exact reason he's probably not interested.)

So pursuit is a 'no-go'. However, I genuinely enjoy the man as a friend of mine and would like to keep him as a friend, without me constantly thinking about him or all the other, lovely, irritating bits that comes with having a crush on him.
<bot>: Met dude online, crushed on him, can't chase him. Want to remain friends without having a crush on him. How do?
