You feel very comfortable together and did so almost immediately. You might have felt as if you've known each other forever, even when you've first met; as if you've finally found the person you've been looking for all along. In many ways, this is true.
It's likely that you were actually involved in a past life; you were caretaker to this person -- their mother or some other family member, someone who nurtured them and cared for them. Those feelings have carried over into this life. You never stop finding new things that you have in common. Your goals and dreams for the relationship are in sync; you have the same desires in terms of all the biggies -- sexuality, children, living situation, spirituality and so on. The smaller things are in tandem, too. This all sounds wonderful, and it is. Even though you might have both wanted to get it all set from the start, planning on how many kids you want and when, what their names will be, when you'll buy a new house and when you'll switch jobs and so on, just be sure that you still leave room for growth, development and change. If you plan things too minutely, you miss out on all the wonderful nuances of a spontaneous life.
