Your friend screwed up. You felt stood up and your feelings were hurt. You no longer wanted to go out. This can be dealt with.
The real problem to me is that your friend is mad at you for having hurt feelings. She is allowed to be mad that you flet hurt, but you are not allowed to have hurt feelings? Make up with her if you must, but try to cultivate another good friends because in the future in any misunderstanding it will always be about her feelings, not yours.
I agree. I don't understand the viewpoint that you should have gotten off the train and gone back simply because that's what your friend wanted you to do. What about what *you* wanted and the fact that you had already
walked there in heels, tried to find her, and were no longer in the mood to hang out? For me, mood is important when it comes to socializing and not everyone can switch back into a happy mood after feeling hurt, tired, or in pain.
Also equally as important, while it was nice of your friend to offer to meet you and walk back with you, unless she was going to carry you, that wouldn't help your feet.
There was also no reason for you to answer the phone again only to upset yourself further by having to repeat that you were going home. After reading your first post, I imagined the possibility of you being in a public place, finally answering the phone again to have your friend try and convince you to change your mind, and bursting into tears in frustration in front of strangers. Then I saw your second post that you'd already been crying before getting on the train and couldn't touch-up your makeup.
Your friend had other friends she was with, so it wasn't like you were leaving her alone for the night. You said you'd talk with her about it later and that should have been enough.
I hope things work out and that she'll answer your calls/texts, or the note you put in her mailbox if it comes to that, without accusing you of being wrong.
