What type of friend was I to this guy?

This happened awhile ago and, now, isn’t that big a deal. It’s just in the back of my head and I was wondering what type of friend I was to this guy.
The story is I used to work nights at a home improvement store. This guy and I started oreintation together. I didn’t really notice him, but he started talking to me about “Band of Brothers”, which I loved. It was random, but I thought what the hey. He was put in gardening and I was put in lighting.
He’d come over every day and tell me jokes. Eventually, he invited me to a group of people’s weekly karaoke on saturday night. After 8 or 9 hours of work, we’d go home and chat online usually for about 4 or 5 hours. One instance, I had this guy in my section who was really pervy and gross. If I didn’t tell my supervisor, the guy in gardening would. I did and I was moved. He’d take me with him to lunch most nights. We helped each other get over some stuff, I stopped him from quitting loads of times, and I started getting curious about what this was. Then, it stopped. I was too afraid to ask him.

Sorry for all the info, but I’m curious what kind of friend I was to this guy. It wouldn’t mean anything now, but I’m curious about what a guy’s point of view would be of this.
