Mike and Bob - my best friend (will be 33 years this fall), has just not been there for me either. Her initial reaction was to cry, when I told her, but since then, she has not responded to emails when I need to talk about my AN or how I'm thinking or feeling about it, and for many months she wasn't answering the phone.
It was when she called to tell me she has a new boyfriend (she's been a single mom for 7 years since her ex left her), that I realized how deeply scared she must be. We've both leaned on each other in hard times and shared good times for so long - especially since her mother died 24 years ago - and this is really the first situation where I leaned and she wasn't there to catch me. Next thing I know, she's found someone new to lean on.
I could take this as betrayal, but instead it made me realize just how much I must mean to her. She's obviously so scared she's going to lose me that she's taking steps to build herself a new support network now. And with this new boyfriend at her back, she has, very tentatively, asked about my AN and really focused and listened to what I said.
It is the first thing in our friendship that is so big that she needs support in order to support me, and as soon as I understood that, I forgave her.
The months where she didn't call or answer emails or calls were very hard for me, because I was deeply hurt, but I did not want to hold it against her - I wanted to find something redeeming about it - because it was so out of character for her. I can tell from her body language and tone of voice that she feels really guilty and awful - that she knows she failed me. I'm pretty sure that would be an incredibly difficult apology to put into words, so I'm not expecting that out of her, I'm just picking up our friendship where we left off. Where it comes to my AN, I'm talking about it just like Jim suggests - sharing my own (hard won) optimistic attitude and going light on details.
Bob - my dad had open heart surgery about 1.5 years ago, and it was shocking how many people did NOT visit him in the hospital (grrr - *I'm* still mad about that because I was the only one of his children who visited and none of his siblings visited either), and yet they all wanted updates. I think a lot of people are absolutely terrified of hospitals. (Heck, my hubby is terrified of hospitals, and from experiences like birthing our children, I know HE is going to need a support network if my AN requires surgery - just to help him with visiting me at the hospital. I don't know if he can handle that first recovery day in ICU at all, since he has so much trouble with regular wards.)
