i dont understand what im doing wrong anymore. I have no problems getting numbers and kiss close. but this is were i get stuck. Me and her will go out for day 2 (sometimes turns into a double with her friend) ill get her isolated fool around then the next day or so i get no call callbackand responce from txt. seriously wtf am i doing wrong?

In my experience day 2s usually sap momentum and attraction levels, this is why the rare occasions I do them I have to go with heavy kino almost instantly.
The way I think of it is attraction is like a fire, you chuck an ass shat load of wood on it in the first meeting then it will eventually burn out, so the more you can add on the first meeting the more of a chance of it still being there as strong on the day 2 and after. This is why I go for SNLs.

Also it could be that you don't get deep enough rapport so at the end of the 2nd meeting they think you just want them for their bodies etc
