Over two years ago I found a wonderful friend via work. I have very few friends and her company was much appreciated. I thought we got on great. Over the years she has been a bit intermittent with contact but put that down to the ebb and flow of life. To be honest, I have my down moments and sometimes aren't the greatest of company. We have always muddled through. However, recently she has been rather abrupt with me in a work context. Admittedly, I was having a down moment of late due to health, family, ex matters but yet tried to remain upbeat and ensured I'm keeping contact/concerned about her and her family.
I'm not the sort of person to give in. Every relationship needs to be worked at. All I want to do is maintain that mutual support but feel that every step of the way I'm thwarted. Extensions of apologies for my being low are not accepted and concern about her well-being met with no response.
At what point do I give up on her/our friendship?
