I'm so freaking out!

So My best friend and I went to the mall and we saw this cute guy. Well I said it out loud and my friend ended up going to talk to him. I walked away to bother my other friend who was working. When she came back she gave him my number and told me his name and his age(20). Well  I didn't think he'd text me cause 1) I literally ran off embarrassed(blushing) and 2) usually guys see me and ignore me.

Well he texted me that night(this morning technically) and I literally stayed up til 3 am texting him and he's pretty cool and chill, and  I think I'm kinda starting to like him( I mean we're still texting) but I'm to embarrassed/shy to talk to him in person and I know I can't because I stutter when I'm nervous. I have no clue what to do! I don't know if I admire him for texting me or even talking to me(especially since my friend freaked him out a little.) or what. Like, I get all smiley and my heart flutters when I see he texted me or I'm looking at my phone every 5 seconds(ok not really like every 3 minutes) to check if it's him. I don't even feel like this about my crush at school!!!

I seriously have no clue what to due. I've also been more cheerful and happy since he texted me but I'm so confused. What happened to " I don't need a man"?! (Miss A) Like that was my song but now I don't know. =.= So confused....
