Search Results: tell a girl you barely know that she is pretty

There's a guy I've been getting closer to over the past week or so (known him for a few months), and I can't tell if he may be interested in me or not. We started talking one-on-one kind of randomly in our group friends last week, and over the past several days, we've elevated from barely speaking to now joking around all the time, him putting his arm around me to say something like "Oh you know I just give you a hard time because I love you!" and texting for a couple hours one night. The most defining moment to me was when we were walking to his car together (we've also been giving each other rides a few nights), and we were somehow talking about pretty girls, and he said "Well, of course you're one of them." It's very unusual for him to give compliments, and he even said that it was uncommon for him to give them after he made that comment. He also suggested one night that if I ever wanted to hang out with him sometime to feel free to tell him and we could do something. Yesterday when he was giving me a ride home (he did offer a couple others rides homes too though, just none of them said yes, so I'm not taking the rides as any kind of sure sign), we passed by some of our mutual friends and his closer friends, and they yelled back at us a joke about "being safe" (doesn't necessarily mean much though).

What do you guys think? Are we just becoming really good friends? Is he interested in something more?
