You have a close, loving and nurturing bond from the very beginning, because you were probably involved in a past life. You had a relationship then in which this person nurtured and cared for you, and those old feelings of love and support are still present in this life. When you're together, you just feel good -- soothed -- as if your partner is a safe harbor for you to come to when you want to get away from the storm of life.
The connection and support comes so easily to you that you probably take them for granted, just counting on your bond with your lover to pick you up when you're down or show you the way when you feel directionless. Make sure not too get too complacent, though; always try to take your lover's good advice, and make every attempt to return the care that you receive from them. That way, you both get the most out of this very beneficial influence.
