To answer #1 if your having fun with her she'll chat more because she wants to, you don't leave in the middle of a game right? Or If She does leave she'll excuse herself not just go dead, I've never stopped texting a girl who I was having fun with
#2 if that's what you wanna try it sounds fine, I personally don't think that'll work well at this point and can be saved for use later to be more effective, but again your choice
#3 no clue lol just a example, I've used the toy story one (yea yea) and you can use any movie in place of toy story (this worked well since I went to her place to re-watch them both to see who's right

but just follow it up with something to lead to a day 2, if I get on my computer I'll send you a routine you can use I like and it's very simple and increases sexual tension pretty easily.
Just read this in a e-mail its very motivating
Listen, what good is getting a woman to respond
to your e-mail if you can't get her phone number?
What good is getting her phone number if you don't
know how to carry on a conversation and get her to
agree to go out on a date with you?
What good is getting a date if you don't know how
to get to hold her hand, kiss her (or get her to desire
you)? - Dave M
