Ok so i went on a "meetup/unofficial date" with a friend, we had fun and she sent me a txt that she enjoyed it.
Well I said im busy for the next 2 days, i wasnt, and we'd meet after, so when i msg to meet she said the night b4 txt me and maybe we meet up, take not date day is 2 days before i travel overseas for 3 weeks, plus she was in a 5yr relationship before this. That night i went clubbing w/ friends and posted pics that she saw ,so here we go this is what happened next morning:

Me:good morning, do u like indie movies @all
her: yes from time to time
Me: there's a good one showing, i can do 7 or 9,which 1 works better for u
Me @ 730: just got back from beach,glad u ddnt say 7, forgot phone@home. Am i going to see your beautiful face tonight?
Her:Hey x, i am with family i hope ur beach day was great!Thank you so much for the invitation!:)Lets do it when u come back from your trip
Me:Im not sure I want to wait that long before i see u, how about tomorrow, would mean alot to see u
Her:Lets keep in touch when !Im suppose to go to xx"3hrs away" with my mom,but its not 100%yet, if i dont, then for sure. I dont like to disappoint:)
Me:Im going to be running errands,if it doesnt go thru,ill make sure u'll b the girl smiling by me, beach day was good, fell asleep on 1 side, were u fishing?

I know i messed up... Is there any way to recover before i leave or as i am away?I really want to date this girl when i come back.

What exactly did you mess up?

I can just say keep being persistent but not in a clingy way, if you still don't meet up amp up the flirting and sexual talk while you talk to her on you're trip. (Examples would be: Roleplay, what you're thinking of doing to her right now, what happened between the 2 of you in a dream, anything to make her visual it so its not cold water when you're back)

good luck

I just kept asking at the end, and i felt i did too much of a cheesy comment @ the end, and got no reply @all
