Need Advice!!!

This guy & I had a drunk hookup a couple weeks ago, we knew each other before but never that way.. We've been talking/flirting every day since & have gone out multiple times. He's told me he really likes me and I really like him. Today I finally asked where our relationship might be going because I didn't want to get my hopes up any higher. He told me that he doesnt want a relationship right now nor does he want commitment because of his last relationship. I was okay with the idea of not being in a relationship but I don't know how to feel about not being the only girl. I really like this guy.. What should I do?
