6 years of friendship is a decent period of time. It is not few months and not 20 years - but still long enough - especially if you were the one doing all the giving. Some people have this way of relating - they tend to take whatever the can. Give very little. You on the other hand - have a tendancyto give. And when such unbalanced relationship ends - the frustration and confusion and maybe anger - are understandable. I am sorry!

I guess the best thing you can do at this stage is deal with those emotions and learn from the experience. Chances are - you did nothing wrong. Think about it - if my good friend did something that would upset / unsettle me I will tell her in aim to have a discussion and move on if we can as friends. If someone blocks you (drops you from one day to the next) - this shows at best lack of maturity and at worst careless nasty behaviour. It could be of course that you have done something - but if she wants your friendship to work - she should have talked to you about it. We are not perfect and make mistakes. If she is a N - it maybe that in her terms you are not supplying her with the Narcssistic ego pets that she needs. I dont know her so cannot tell you about that - however - my bf's ex wife is a N - and it always has to be about her. She is wonderful. She is clever. She is charming. She is adorable. When you put a boundary up and either not involve her or she thinks you dont like something she has done or said - you become a monster in her eyes. Maybe you have stood up to your frien in a certain way that she is not able to accept. If this is the case - then this is her issue, not yours.

Few of my past friendships ended because the other person stopped communicating. I find that these relationships were based on some lie. I know its harsh. But for me its true. I do not mean to say I was lying or the other person was. Its just that the connection was based on something other than true care. If I cares enough about that person and did not want them out of my life Id take to them - as in the case with my best friend. And guess what - we normally find a way back together.

I think its an automatic reaction of some people to look inside and blame oneself. But if you examined things and cannot find any incedent - and if you contacted her to find out what went wrong and she does not respond - put it down to experience, deal with your emotions and maybe you have not lost something that speacial...
