In a way it somehow mirrors reality. While dating someone whom I share mutual attraction with,the feelings are intense. Even simple conversations take a life of their own. But the real test comes when commitment steps in. All of a sudden, there are things you cannot talk about, things you cannot share (for one reason or another) because it might cause misunderstandings.
Ironic how we sometimes can be completely honest with strangers and keep secrets from people close to us.
