Help guys! Your opinions, how much he should text before meeting in person to know if he is interested?

We meet online still didn't manage to meet in person but we are gonna schedule meeting... So my question is how much should he text and invest before meeting in live? If he don't text much or asking a lot of questions does that mean that he is not very interested or is normal? And also it is normal to want to meet very fast even if he don't know a lot about me?
