Waccoe.......welcome to the forum!
To answer your question as to "what is the best". I feel that the "best" for the both of you is to back off and give her at least one year of space. understanding, that, of course, there are no guarantees on either side.
Also, in life, when we give of ourselves to another person---it is (should) be given as a gift. Otherwise, it is just a manipulation. When we giveof our selves, there is never any gurantee that we will receive back in kind.
Also, I don't suggest that you sit on a shelf, just waiting for her. You would do best to go forward in your own life.
At least she is being straight forward and honest about the situation with you. You will come across as a more confident and stronger man if you honor the request.
Honestly, she does Need the time to focus on the hardest journey she probably has ever faced. It is harder than you can imagine to get into genuine recovery from any addiction----and the responsibilities of and demands of a relationship is a great risk for relapse, especially, in someone who is struggling in new sobriety.
