My psychic impression is that she still does care, but is hesitant to take you back. Your only chance is to make some changes in your life, and offer proof that you have changed. Check out an addition program. Try to understand why you have issues with weed, and try to resolve these. Shower her with appreciation. It feels like you still have a chance, but you will have to make changes fast and prove it to her! She’s ambitious – I see her doing something like healthcare of counseling. What are her goals for her life?
