It's important to spend time away from each other. People need that independence from each other and to have their own quiet time. Relationships are hard; you have to work at them. If you think you're going to find someone whom you'll always be completely fascinated with, it's not going to happen. Having your own space — it doesn't have to be much — allows you to remain fascinated with each other. It also keeps you from taking each other for granted, which happens when you spend every minute with someone.
