Input: I've known the friend for 21 years. After university I worked, got some more qualifications and saved up and got my first place. She's travelled the world coming back periodically.

Over the last 10 years she's become increasingly negative about me, saying I'm boring, flat is not very nice etc and about other people around her. This weekend I'd arranged for us to go out because she'd gotten upset about not being thin at the gym. On the way out I asked her if she would mind if I dropped her off at the train station because I had to pop and see another friend.  I'd pay for the train ticket etc. She then refused to to talk to me for the rest of the journey. When we arrived she told me that I was selfish and make every about me and she's always the one that makes effort in the friendship.

I'm really hurt by this and feel it's really unfair. I've spent the last few years fielding her calls etc when she's down, organising days out and I've joined the gym with her so she didn't.  In the last year she's rarely been free at the weekend, she's busy with work friends etc.  So I've started to go out more with other friends and picked up a few  hobbies. I've had to rearrange some stuff recently with her due to illness and work stress but thought she understood why. She also didn't come to birthday (at weekend) because while she read the text I sent she didn't reply for a day and a half and I needed to book ASAP. I didn't think it would be a big ask for her to get the train as she'd previously said that's how she was going to travel that day. I feel the outburst is just the latest in a long line of emotionally draining interactions. I don't want to throw the friendship away but equally I've spent the rest of the weekend feeling so down and this isn't the first time. If I called time, am I the asshole?

being not sure I want to spend time with an old friend any more
