'Relationship' Problem

Ok guys, here we go:

About two years ago now (so endish of Y11) i met a girl online through an online site. We really hit it off and after chatting for about 6 weeks, met up - first time good and we decided that we wanted to start dating each other, but second time less so. (Granted i was really depressed around this time which i think had a factor)

anyway over the past two years, we've peridoically (normally a chat on msn bout once a month) and this continued up until a couple of nights ago.

The last few nights we've had a couple of 'intimate' chats and are now both kinda confused. She's started dating someone (but not in a relationship) and i like someone else (who i know i won't keep contact with after college if i don't do something about it)
But i still kinda like her. I know what i saw in her back then, and the reasons are all still there.

But we're both worried that we've just gone round in a two year circle, and are taking the 'easy way out'.

any ideas?? guys and girls help wanted rly
