If the pushing to meet you is something to which she is contributing, look at from her point of view. She already considers you to be "in with the in crowd" so to speak. You are the one with history with TPG; you are the one he went back to after a break up (must be something special there); and he probably talks to her about you as much as does you to her. She probably fears rejection. Or that if you don't like her, then TPG will ultimately choose you and go questing for a new girl you do like. Texting during your time together sounds like insecurity to me.
