This is my first post on this site; I'm not sure if it's in the right section. (sorry)
Persistence is a great value to display to women IMO. It shows that you're going to get what you want despite the obstacles.. But, where is the borderline where you come off as needy or desperate?
I have in the past given up on girls way too early after a girl did not reply to one of my texts or calls.. Just this past weekend this came back to bite me in the ass. A long story short, I gamed this HB10 about 6 months ago; # closed it, and then wasn't able to set up something due to both our schedules. After the first phone call, I sent her a text which I got no reply. I just said fk it, because I figured she was just making excuses and wasn't interested. Saturday night I run into this chick again and was not phazed at all by her and I approach her ask her how's shes doing, etc.. She then drops the bomb on me asking me why I never tried contacting her again. I tell her I tried, but never got a reply and moved on. Much to my surprise she says she never got the text or she would have most definitely responded.
How much time do you give a girl before giving up on her? How many missed calls or ignored texts?
I have run across another interesting situation with a girl I met in one of my classes this quarter. I got some IOIs from a girl and followed it up with a # close a few weeks before the class ended. I got busy during the holiday season, and spinning other plates that I totally forgot to call this girl.
A day after the final I sent her a text laughing at how fast she ran out the door and how happy she was to get the class over with. And in the text I joked that I bet she already sold the book. She replied like 1 minute later with "Haha, no I didn't sell the book yet, did you?"
Now, here's my error, but I don't really give a shit. I go with my instincts most of the time with my game and really don't give a shit about the outcome either way, because I do well regardless. I replied to her text a few hours later at about midnight with "No, I didn't, but I would like to see you again. Maybe we can celebrate being done with that class.

"
This was last Thursday night and I still haven't gotten a response. How much more time do I give her to reply? And, do I contact her again? And, if I do contact her again how do you start up the conversation again, without looking desperate or needy? Do I joke about her not replying or what? In the past I would have just forgotten about this girl, but I feel I move on too fast and maybe should be a little more persistent.
Sorry, for the long post.
