you know what, you should just give her her space and time. Leave her alone for awhile. If you're lucky, she may realize that she misses you talking to her and might wait for you to sms her again. So you stay out of contact with her for a couple of month. Then you try your lucky again by smsing or calling her, just asking how is her and stuff. Just to show you still concern about her well being.

On the meantime, you can keep urself busy with whatever work you can find.
