She might just be trying to establish healthy boundaries for you. If she does care about you, genuinely, then that is what she would do. Because if you come to depend on someone for something they cannot provide for you, such as being your surrogate parent, then that could wind up in a world of hurt for you - which it sounds like might be happening. In such a case, the best thing she could do for you is to try to set down some boundaries to protect you, and hope that you will seek out proper therapeutic help for yourself.

Sometimes the way people try to be kind to us, is not the way that we were conditioned in childhood to receive affection, and it can be very confusing and hurtful. But please try to have faith that she wants what is healthy for you. I know it can feel really sucky, though.
