Empty

 A man does not love you. 

He lusts for you.

The attention he pays to you is only to get an outcome for himself. 

Once he has that, you are nothing to him. 

Do not mistake his talking to you as his interest in you. 

Or that he is vested in a friendship. 

Be guarded and respect yourself enough to say "no". 

He will move on very fast when he hears that. 

And you will see how genuine he was. 

Lust is not love. Attention to you is not a commitment. Persistence is not interest. Words are empty.
