I still have a crush on a girl who I met when I was 16 (I'm now 30) and I haven't seen her since then. So rest assured, 6 years is nothing.

To complete this flawless "victory", let me also note that this is after calling her and finally confessing at the 7 year mark, and her claiming during that phone call to have found someone to marry. It didn't stop me, it just made it hurt more. I'm not saying I didn't love others in the time after, but I would definitely crawl over hot coals to see her again, if it were only that easy.
