Hey,
It actually just sounds like an everyday thing. But there's the problem with online gaming. It's hard for them to really judge your personality. If you want to be online gaming I say use emoticons and just go for funny and little less on the cocky.
Btw, cocky is best followed up with either something that makes it funny or rewarding like "i'm not easily impressed, but I found it cute.
"It's about being positive and having a good time, not putting every girl down. I say stop using negs after the attraction phase. If you must, do it when they do something bad, i.e a shit test or disrepect to you.
If she doesn't come back to you, I say don't apologize, but you most likely lost attraction after that. Then again don't over think it. She could have been busy or sick again

. It seems to work like a charm. Plus online you really have to be more careful not to be too cocky because in rl you can always laugh or make it really obvious your joking
