...and he's not going to string you along until he's ready because his time is valuable to him as well.
It doesn't take a man long to know that you're the one. It won't be your job to prove anything. In fact, what will happen is that he'll court you for this reason alone:
To see if you're attracted and willing to commit to him. He already knows that he likes you and wants commitment with you.
The dudes who are testing to see if there is compatibility or if they like you enough ARE PLAYING. If a man has to test to see if he likes you enough then RUN. Even if you get him, it will be a very one-sided relationship where he has all the power. You'll feel anxious all the time and fearful of abandonment.
