Was I being a Jerk in the end?

Yes. Girls take everything too seriously. Trust me, I know. If you really didn't mean it, then you shouldn't of said 'sike'. With the misunderstanding, she probably was sincere when she said it was fine after you apologized, but after you said sike, she was bound to be done with you. In the end, that was a jerky thing to do and now you've missed out on her because of it. Hope this helped though(:

Apparently u did but u can try to give it some time and talk to her in person about the joke

That was kinda dickish on your part. That might have not been the best thing to say, but she could've taken less seriously.

What happened to cause all this though?

Smooooooooooooooooooooooooooth.

Uh... Sortve haha, I think she took you're first apology serious, then when you said sike, she must've been like : seriously? ( nobody got time fo dat! )

For someone you just started talking to yesterday, that was just horrible. Overall, yes you did too far... wayyy tooo far.

Yes you did , but she'll get over it , just keep apologizing and trying to make her see you mad a mistake

Let's say yesterday was the first AND last time to talk to her! :P it was horrible, yes.

I think far is an understatement. I think you went full stupid bro... no offence but why would you say that? Makes you look like such an ********.

Yo, grow up
