Hey man, just small tips:
Avoid the kisses and anything childish like smilies. I only every use smilies if I say something that can be taken in the wrong way, then I'll wait a few seconds, then put a wink. I guess I use them in the same way I would if I had a cheeky grin in person, just so she knows you were only messin.
But you played that quite well. Just don't try too hard to arrange a meeting, make an offer and make it no big deal. If she flakes then show her some disinterest and wait for her to make some effort before you try again. There's quite a few posts on the forum about that kinda stuff. Good luck bud
