Help me! Problems with a guy?

Ok, so there's this guy. We see each other a lot at parties since we know certain people. i got his Sn from my friends and we talked for a long time. I gave him my number and we text A LOT. I am crushing on him, and my friends think hes obsessed with me. He seems like he's flirting, and I think he likes me! What should i do? No stupid answers please! I'm so confused!
