Delusional Friendships

Her email- 

R, 

I don't know how to word this and I am debating in my head if I should write it at all. But, it has been bothering me for a while and if anyone can help me I think it's you.

I really enjoyed my friendship with Z, and felt that we were very close friends. It seems that all of a sudden one day the frienship ujust turned off. I want to figure out how I hurt her so I can try to make amends, it really eats at me that our freindship ended so abruptly. I am not expecting to "pick up where we left off", I just want to right any wrongs I did. 

I was wondering if you had any insights that could help me piece this together? I don't want to "drag you" into something 1) because I don't think there is a "something" and 2) you have enough on your plate. I just know that you are very aware of people's feelings and know me and Z well enough to hopefully be able to help. 

Please don't share this with Z, or anyone else. I have tried asking Z but she brushed me off. I don't think you asking her "head on" would help either, but again, if you had any insight I would really appreciate it.

My response -

Hey,

Sorry I haven't had time to respond.

I wish I could really help you. Honestly, I  don't know. I think it's natural for friends to grow apart. It's definitely a hard reality. But isn't that life? I'm not sure what happened between you two. I really try to stay out of everyone else's business. It's just a simpler and less dramatic way to live.

I do know that every single one of us has not had the "easiest" life and sometimes taking space is the only way to function. Less painful than opening up to those around us. I know that I have taken that approach.

I'm sorry if I can't be more help. Sometimes, I miss the days when we were younger and more naive. When life was "simpler" and we were all just getting together for a potluck. But sadly, and maybe realistically, those days are behind us. We have all had to grow up. And that's part of life.

I guess the question is "now what?"  And for that I definitely do not have an answer.

R :)
