First of all, it takes MUCH longer than 6 weeks to decide if you’re compatible with a girl!! There are interests to consider and more importantly temperament. You need to judge carefully if the way you interact with each other over time is good or not. If all goes well for at least 6 months, maybe decide to ask for an exclusive relationship.
Don’t ask to meet up. Answer her messages if there is reason to do so. IE: if she asks questions. But make the response short and kind. I think she must be very young as most mature women prefer the guy to chase, not the other way around. Take it very slow and don’t push for anything. Use your logic to determine if she is really a good fit for you. Time will tell..
