A man must live for his purpose with full commitment or he will never be completely fulfilled. Like so many aspects of male-female relationships, this can be a catch-22 situation. A woman wants passion directed toward her, but deep down doesn't want you to divert that passion away from your mission, because doing so will render you a different man than the one she fell for in the first place. My personal experience is that if you channel your passion into your chosen purpose, you will be happier in the long run. And that happiness and feeling of contentment can then be channeled back toward your loved one. Channeling all your energy into another person while neglecting your purpose in life is a recipe for self resentment. Don't do it.
