Right I got a girls number last week and saw her out last night. Texted her a bit last week but she lost interest. Texted her this morning:
What was I saying to you last night? I was rather gone!
Her: I don't remember much either. It was probably drunken ramblings though. Hope you had a good night x

Any suggestions for building comfort/ negging/ progressing? Think she isn't too interested at the moment.

Cheers guys

Text game is a real bitch if thats all you have, you can build through it but you really need to make an appearance in person to really influence her and to progress better.

If you got her number by already gaming on her then think of something funny fromt that night to joke about. For example
I met some girl at the club and she hates techno but started dancing to it and was fairly decent. I remember i made fun of her for that so the convo starts with
Have been working on your moves techno!

HB: Don't be jealous that I can dance.

And then it moves to a simple negging game. The point here is building up some comfort. If you didn't already do this then it makes it kind of hard.

Also try to stay away from the "I was drunk last night don't remember too much" make yourself sound like u had fun and wasn't thinking about her.
