Friend mysteriously stopped speaking to me
A little over a year ago, I made friends with someone associated with my company. After the person was no longer a client of my company, we started spending a lot of time together. After a first casual visit to her home, I met her extended family on both her side and her husband's side. We spent various holidays together, and she and her family were part of a very small group who celebrated with me on my birthday. This was not an ordinary friendship. The relationship wasn't perfect, but it was a close friendship.
Then, all of a sudden in early December, she stopped returning my calls and emails. I think she may even look at the caller ID and decide not to take my calls. I can't even identify what I did to offend her. I've even tried writing to her husband to see whether he can help me find out.
After three weeks of attempting, including putting read response tracking on emails, I'm finally giving up (partly at the suggestion of my other friends). Do you think we might ever be friends again? Should I?
