Confused!

So as mentioned in my previous note, I went on a date with a REALLY cute RM last Saturday. At the end of the night I really didn't think he liked me. I'm still really confused about that part ha ha. Well Monday night he was gonna text me after work, so when he didn't i figured okay, he doesn't like me now i know and I can date other guys. Well Thursday I went and got my nails done and went bowling with Rach,Casey,Patch, and Lady. While we were there Brendan texted me. Just to see how I was and such. Which is when all the confusion started AGAIN. So we talked for a bit and he invited me to hang out with his buddies on Friday night. So I figure what the heck I'll go. Should be fun right? Well he said he'd call me when he was on his way over there. Should be around 7:30. Well about 745 he calls me and says hes running late and will call me when he gets to Spencers house, he just wanted me to know he didn't forget about me :) well finally around 930 he calls me and tells me to come over to spencers. So I do and its just us 3 for about 10 minutes. Than Derek shows up and wants us to go to Johns apartment. So we head over there and meet up with some more friends. There were a bunch of girls. One of them (the one that Brendan referred to as "One of the guys") bugged the crap outta me she NEVER left his side. Well finally he came and sat next to me on the couch. But I didn't like her! LOL. So at the beginning of the night though, he let me have front and opened the door for me and everything Do you do that for just a friend? I really don't know! But at the end of the night I was freezing so I ran to the car and he didn't open the door. The night ended with another hug. But he hugged the other chick too. SO I dunno anymore. HELP lol.
