Girl meets, has fun, but doesn’t call for “exclusivity”? This means she is enjoying the buffet but doesn’t want to finalize the menu. If after two months the girl hasn’t given any signal, then there are high chances that you are just a placeholder for her until a better option is found.
You are terrified that you’ll scare her away. But the truth is, when someone truly loves you or is serious about you, a question like “What are we?” doesn’t frighten them; it actually brings them peace. He’s only afraid because, deep down, you already know the answer might be ‘No
I think you should pull back a little. When you are always available, the next guy doesn’t feel the need for commitment because he is getting everything for free.
Anyway, if the girl were actually serious, you wouldn’t need to ask this on this forum. Silence is also a message, and you are simply failing to read it right now!
