Have been having a tough time lately with things, but said friend has been very supportive. We have been friends for a few years now and have lots of shared experiences (went to uni together, lived together, gone through a lot).
Anyway, she recently got a new boyfriend after being single for a couple of years. I'm single FWIW.
I understand that in new relationships, people do want to spend all their time together, honeymoon period etc etc. But she has blown me off a lot recently and things culminated in her treating me appallingly when I said I couldn't do him a favour (he was travelling to my area for work and she asked if he could stay, I said it wasn't convenient. I barely know him btw).
Basically she got huffy with me and I told her, privately, that it was a bit of an unfair situation to have put me in. She went postal: denied things, made things up, basically tried to make me out to be unreasonable.
What is the best way of letting this friendship go? I know it sounds bad but they do say revenge is a dish best served cold after all. I don't want to be cruel or vindictive but I do want to make a point
