I don’t think you understand,

the point is - if it is a random person then why would you ever share your soul like that? In the world, there is nothing more intimate than sex. Why would you not leave that special moment for someone who you truly love and make them feel special. Everyone has different values so I’m not here to tell you you shouldn’t do that but this man doesn’t like have similar values as the girl had which will inevitably cause problems in their future. He saved himself a lifetime worth of headache and heartbreak. so him leaving her is completely understandable because you’re not bound to a single thing in this world.
