Thanks Indigo,

I did as you suggested and called her again and left a message saying "hi, haven't heard from you hope all is well call me when you feel like it". I left a message like that a couple of weeks ago too. :Last week I emailed asking if she and her partner would like to attend a concert my brother us singing in, my treat. No reply.
I hope she is not having a hard time, but if she is and I am not someone she sees as a support, then what use am I anyhow? And how could I ever expect her to be a support for me? I just don't get this.
With the exception of when I crashed and burned 4 years ago, I don't actually depend on her a lot, I don't really depend on anyone. But I enjoy her company and it's nice to have someone to hang out with once in a while who isn't family...

well thanks for 'listening'...I guess I just need to let go and grieve and move on.
