Guy Texts Me Every Morning, Does it Mean Anything? Is it a turn off if I call him "bro"?

A few nights ago I got a random facebook message from a guy I met in college. I think he *might* like me because he'd stare a lot in class and go out of his way to talk to me. Anyway, during the convo he asked me how I was, if all my time was dedicated to working these days, and suggested that whenever I'm in town I should "hit him up." I asked him how I was supposed to "hit him up" without his number, so he messaged it to me, and told me to shoot him a text sometime. I gave him my cell number too.

For the past few days we've been texting back and forth. He always texts me first, and pretty early in the morning, this morning he texted me around 9:30pm and said “good morning!”

We were on the topic of video games and I criticized one of his favorite games, because it’s insanely hard. Today he wrote “dude I’ll help you beat this game. You can’t give up on this game.”
Does calling a girl “dude” mean you aren’t attracted to her? (btw I called him “dude” first) Is it okay if I say “thanks bro”?

never ever ever ever EVER call him bro, dude, man, etc. My brother once told me that when girls say things like that it is a complete turn off and no girl should ever do it. everrrr. especially if youlike him. it'll scream just friends, and his like for you will dissipate fast

major turn off to call a guy bro or dude. especially if they like you because all they see if you're legs closing and you're mouth blabbing on....
