hmm, so what exactly do you want to express?
1. Do you think that she will tell you her whereabouts every time, which is an implied confession to you?
2. You've known each other for a long time, so you are friends. That is to say, you don't often meet each other in reality, but you are limited to online chat.
3. In fact, sometimes online communication is a little more relaxing than real communication, which makes people have many illusions and will be misled by some actions of the other party.
so I suggest you don't think about it yet.
