Would you feel like you were in the wrong or your friend was?

Something is definitely up there with your friend. Weather it is something concerning you directly or something within her life of this I am not sure. But,sometimes,some people back away with anything concerning death,they become nervous,to saddened and the like, why this is with some could be various reasons. I sincerely do understand you needed to just talk to a friend as you were very down with what was occurring in your life as well, and she really should have responded to that call for support as well she could have leaned on you with what ever is bothering her-to,as that's what friends do for one another,in good times as well as not so good. So,I can understand your hurt feelings as her behavior was not friend like. I know she means alot to you as you said that is why your asking on the situation here. You could give it one more try,in the sake of friendship and for the friendship you thought you shared. Either call her or talk face to face,which would be better if possible,let her know you are upset with what has happened between you both,and that her friendship means alot to you as you have enjoyed it and ask her could we talk it through to heal what ever is wrong. If she responds well do just this,if not then one easy lost was not worth having,as you will have given the effort to work things out. If she continues on in this note,she may not have been the person you thought she was at all,just a rainy day friend that when it poured to much or to hard she ditz you,there are people like this and if she turns out to be one your well rid of her and her negativity. Move on in that case til one comes along that does know the true meaning of friendship as you do. It's a big world and she does not add up to the whole,she takes from it.
