So this girl who is coming back to town soon who I havent seen for 4 months has been keeping in contact with me. We text every month for a short period. She last texted me a month ago, she texted me first and she ended by saying we should hang out when she comes back to town soon. She hasnt come back to town yet, but is it worth texting her or not. If i text her will it then push me out of the driving seat and lose any benefit there might of been of her currently chasing me and suggesting we hang out? I want to text her but I just dont want any progress to be fucked up.

You know, in the PUA world, every move, every little progress done, maybe means something, conveys something. Now, the fact that you just grab your phone, and send her a text telling her something before she does to you, isn't going to destroy you, doesn't mean that your game is ruined! That you're fucked up and you've turned into a Beta Male. No, what if, you just plan to do something fun every week, be genuinely interesting, genuinely fun, and for the time she arrives, you will tell her that's her lucky day, because you got something so amazing to do, and she won't want to lose it, you're inviting her, with friends or whatever, and she has to go! So this 'little move' (Sending the first text message) becomes genuine and not a mindblowing fact, of "Should I? Now or later? Today or tomorrow? After she speaks to me or before? Omg I don't know!"
This way it's not going to be something robotic, something you break your head doing, something that isn't going to be stressful, you're with me?

Good luck.

Text her just don't overdo it. Nothing wrong w staying communication. Make her laugh, feel good texting is just another outlet for brightening perhaps an otherwise dreary day for her. Sure, why not text away.
