Over the past few months a close friend (A) and I have been becoming more and more distant. It started when I didn't tell A about mutual friend (B) having a go at me. I didn't tell A because I thought it was for me and B to sort out without putting A in the middle. However B did tell A and A got the hump because she thought I was keeping secrets from her (forgetting all the other information I had confided in her over the years). A didn't ask me why I hadn't told her and instead stopped telling me anything personal in a kind of 'tit for tat' behaviour.
We still meet for coffee occasionally but A clearly has decided that there are things that we used to discuss that she no longer wants to share. I've recently had a major family crisis and I'm reluctant to tell A about it after her blocking me for months but feel awkward not telling her. Part of me thinks that if tell her something personal then maybe she will start to open up to me again but the other part of me thinks that if i confide in her and she carries on holding back information then I will be mightily pissed off and it will kill the friendship completely. I'm not sure I trust her enough to tell her. WWYD?
