We have to recognize, understand and respect each others limits. Adjust our behavior accordingly. Many freinds for many needs. Also, changing an stablished pattern effects everybody in the pattern. Shifts in relationships are scarey. Sounds like she is dependant on you and needs to take a peek at that. Hope you can find a way to both reassure her and move on at the same time. Maybe a special meal where you honor the special year of closeness you shared, give her props, clear the air. She has to find her new balance too. Good luck.
