Just forget him. He is expecting second child with her that is imply he want that girl or have feeling. Don't entwined yourself into married person cause it will make your life harder. How could when he already have wife and child still confessed his feeling for you, how irresponsible person he is. Maybe he want to sleep with you, just beware for that kind person even if he is your best friend. Better ruin your friendship rather than doing something awful like cheating with someone husband.
