Personally, I don't use text messages much, but when I call a girl I known just a little I usually go like this (I think you can adapt it to SMS) :
- Hey, how much did you miss me?
(playfully - I'm already assuming that she did miss me, the question is only how much..)she usually plays along, if not and says something like
- I didn't miss you.
or
- Not much/ Not at all.
I reply (again playfully)
- Oh you are such a terrible liar!
they usually don't have answer to this other then laughter.
Then when you sort of "force her" to admit that she misses you, you can suggest to go out
- I'm going out to XXX, you can tag along if you want.
I personally would never call a girl to a bar. Ever! I'd call her to go shopping with me to a Mall for example. You don't need to buy anything, just say you don't like anything in that mall.
Girls usually like shopping and also there are hired guns so I always try to create situation where I can make fun (aka NEG) my girl in front of the girl working there. Works perfectly to get here emotional stat pumped up!
