<human>: Can you condense the text into a few key points?

I'm a 22 year who just took a job abroad for at least a year. My 20-year old girlfriend who I've been with on-and-off with for almost 2 years is still in college, and though we love each other very much, I truly want her to be happy and I don't want the guilt of stealing these great years from her through a miserable, long-distance relationship. I sincerely hope to see her again once I get back (and she has expressed the same), but I'm not naive enough to think that it's guaranteed.

Anyway, we had been chatting online a bit, but that became really hard so we eventually decided to stop talking for a while. I still have the strongest feelings for her, and with no real outlet.

I was wondering how appropriate it might be to send a letter to her parents (specifically, her mom via facebook) just telling them how much their daughter meant to me. On one hand Im obviously biased and dont want to come off as some creepy dude channeling love letters through them, on the other hand I've met them a number of times, they've been very nice to me, and figured that any parent would like to hear how great their kid is, (possibly) even from an ex-boyfriend.
<bot>: In love with this girl, though we're no longer together. Do I send her parents a note telling them how wonderful their daughter is?
