Should I ask him out?

Despite having known one another for years, we have been friends for more than two months. Although I've always liked him, I never gave it much thought. He assisted me with my dress on prom night (it was really long and puffy), and we took group photos. I think he's interested in me, but I could be misinterpreting his signals. We spent a few days hanging out at school together, and whenever we talk, he confides in me when he can't tell me everything. Stress has made me a little aloof lately, and I'm not sure if I should just ask him out. I'm not sure if he feels the same way about me, but some of his buddies advised me to ask him out.
