I am very new to PUA and Game, so just looking for some people to hopefully shine some light on where I am going wrong.

When I sarge online I generally don't have too much trouble getting a number from the girl if I can just get an initial response to start the conversation.
My downfall is what goes on after I get her number. Generally ill wait a few hours or over night to text them and we generally talk for a few days. During those days I will suggest meeting up (most of the time I will ask, sometimes even tell within 4-5 texts.) but usually get some lame excuse not to meet up and it tends to just die down until we don't text anymore.

Pre number, I will neg them a lot and get them to demonstrate their worth to me and it tends to work pretty well, but this just isn't me.
I am generally a very open guy and don't have much experience with relationships or dating, so playing the smooth operator character doesn't feel right.
I guess it probably stops abruptly because I cant keep the disguise up for a prolonged period of time.

Example;
I managed to get 2 numbers yesterday one I texted a lot during the day and she is just playing hard ball. I asked her out and she came up with an excuse not to meet.
The other gave me her number last night and I haven't messaged her yet.
What advice do you guys have for me?

Thanks in advance!

Work on your inner game. That seems to be you biggest sticking point. And that's going to be solved once you start going on more dates and getting more experience.

Girls flake for various reasons. Don't think too much about it.

And continue working on your inner game. Don't invest just in online dating. Go out and get reference experiences elsewhere.

It's easy to believe in something after you see it work. If you'd all already seen a certain strategy paid off for your. Even if you don't think that you are "that guy" whatever the fuck that means, you can move towards becoming him if you really WANT to be like him. You don't have to throw it all out, put it your back pocket, so to speak among your other tools. Maybe you've only been teased by the idea of being that guy but haven't been SOLD on the benefits. Again, you just need more experience.

Why don't you try calling her and talk to her? Only time I ever text is if I'm too busy to talk.
Give her a call, spend about 15 minutes connecting with her, then say that you have to go and suggest that you meet up for a drink.

I would have just said " let me know when you're up for it" and leave it there.

Look up Coach Corey Wayne on youtube, that's what he would tell you to do. He has taught me so much.

For the other girl you can chat on the phone for 5 minutes, then ask her when she can hang out with you.
