A relationship is about two people, not just you. If you want to back off for a year, that's great but she gets to make her choice too. Love is a bonding between two people. Neither wanting to take a break for a year nor wanting to date someone else rises to the level of "love." But that's OK. If there should be any real elements of love between you, you'll decide to back off your sabbatical and she'll come back much wiser. Otherwise it wasn't meant to be.
