Cuddling, flirting or just a close friend thing?

My best friend (who is a guy) and I cuddled the other night. I have feelings mixed feelings for him right now, I'm stuck on him and another guy basically. Anyways we cuddled the other night and we normally don't do that. I mean we flirt a lot but that's how I am with most guys. So I want to know if it's a flirty way to say hey I kinda dig ya, or something you can do with your best friend and not mean anything?

Also this was his idea not mine, he invited me to come look at stuff on his laptop and had his arm of my side of the couch.

So give me your opinion on what you think it was about.
