Firstly, everything sounded good. I've done the same thing myself... Mistake = Not stepping up and making a more confident overt suggestion.
Minor mistake = texting so much. Nothing wrong with this, everything got built up so much, you either wanna space it out, or make the next step. You didn't make the next step. (refer to mistake number 1

)
In regards to this...

"what kind of trouble are you causing?" answer: "Me? Trouble? Never! Why?" I took it as a negative repsonse
Did you steal that line from me? I used to use it a lot, and shared it to a few.
Either way...
1. it's a useful line, use it.
2. a lot of the time girls will respond VERy similar to how your one just did.
i. this is good, because it's a response.
ii. Every answer, is a good answer (:
When my girls answer like that, I respond with "ohhh, okay, What kinda trouble have you been avoiding then?

" or any other kinda shit.
You don't know why you took it negativley? I do... You were expecting a certain response, you were hoping she'd respond a certain way, probably by telling you what she's been up to. This is something you'll have to stop... because...
1. Every answer is a good answer
2. You'll feel crap everytime you try to 'set up' a response and it doesnt go your way.
Just some advice I thought would be useful to you.
