Deepening intimacy without defining a level of commitment is dangerous. It`s like going mountain climbing with a partner who isn’t sure she wants the responsibility of holding your rope. When you’ve climbed two thousand feet up a mountain face, you don`t want to have a conversation about how she feels “tied down” by your relationship. In the same way, many people experience deep hurt when they open themselves up emotionally and physically only to be abandoned by someone who proclaims he’s not ready for a serious commitment.
