Hot girls are busy a lot of the time.
I wouldnt worry about what she is doing. If she is interested, she will right back.
If she is busy she will wait till she has a minute and then right back.
If she is with friends, she most likely isnt going to sit there and have a d&m with you over SMS.
Also, SMSing at night can be a lot better. Mainly because girls are less busy and you can get her on the phone a lot easier.
Cut the SMS down as well. Get her on the phone. The SMS is just a gateway communication to the Phone \ meet up.
Shouldnt be used for idle chit chat.
I spent a lot of my money on booze, birds, and fast cars. The rest I just squandered.
