Most of the friends I've lost over the years were people I knew in real life. Some of them we just grew apart- we can still talk to each other on a friendly acquaintance sort of level. Strangely enough, I became close to my internet friends of years and years and I went to visit them in person last summer. It was awesome. This is coming from someone who used to have an internet-paranoid parent.
But yeah, that sucks. It's better that she's just leaving and you didn't get into a fight or anything. Maybe you'll bump into each other online in the future. I know I see people from this one forum I used to be on /everywhere/. Seriously. The internet is kind of small. XD
