((((((BEautifully mistaken))))))) You must have been very important to her for her to need to do something so absolute to make the break. Strong emotions are like that. Strong attachment swings more easily over to strong dislike than it does to not caring. In that way, she may still feel (and rightly) that she still feels connected to you and needs to really do something extreme to break that connection. Chances are it won't work for her; only time can do that.
You have behaved VERY honorably, Beautifull. Take comfort in that. Try not to take her manner of handling the end of your friendship personally. As someone who often gives art myself, I know it is a way of giving yourself, and destroying that feels like a direct attack. Don't let that feeling take over. It's her issue now. You done good. (Hug) Time to move on and let her work it out. Huuuuuuuggggggssss, hope that helps you feel a little better.
