So, my friend got a dose of my not nice behaviour. I am thankful he hasn't blocked me and assured me that we will always be friends. But he has become more distant and aloof. And I am really struggling to cope with this new reality. My first and really strong instinct is to cave in and write him a goodbye mail about how I am unable to cope with his indifference. To cut him out of my life in short. But, after having made a song and dance about promising to change I can't very well cut and run. It also gives off a mean and petty look as if I am sulking. Any tips on how to cope? I keep bashing myself and drowning in regrets and "if-onlys". I also have one-sided feelings for him which strongly urge me to run away now before he gets married some day.
