There are several things you can do. I have two techniques in mind to at least get somewhat in touch and they are both reasonably effective to extremely effective. Depends on the girl.
Technique 1:
Send her this:
“Aliens are coming to abduct all the sexy people off the planet and force them to breed. You should be safe, I just wanted to text to say goodbye.”
I have got some good respones when I used this technique, and one "bad" respone (it actually wasn't that bad, she just was like "Seriously? -_-", but I bet she actualy had a laugh at it)
But...., you could also use this one (the more effective one):
Technique 2:
You: "Congratulations"
Her: "Lol why, forwhat?"
You: "I was just thinking about you, congratulations"
Every time I used this one, I got good responses
Hope my advice was useful (;
Success
PS: Pls tell me the results, I am curious if this shit works the same for you are it does for me
