Tense tension

I found myself more than a little lost for words last night when a long unseen 'friend' appeared on my msn list. We had a brief chat and it was all very nice. It's been ages since we have talked and I thought he'd blocked and/or deleted me. It didn't go on that long. I'm so scared of scaring him off by coming across desperate, but at the same time I don't want to appear disinterested either. I'd like to get back into that friendspace we once were in, but I can't pretend that I wouldn't like to step it up as well. The tension there may be too strong for us to be friends but I would like to see him more.
