I'd say it was unrealistic expectations of me, and inflexibility.
Then getting upset when I deviated from the plan she had in her mind.
She wasn't trying to be unkind and was very generous in some ways, but couldn't see me as an independent person with feelings and boundaries.
For example, she had very specific interests in music, books etc and "recommended" I read them.
Obviously this is ok for a while, or for one or two things. And I liked reading.
But then her expectation was I spent loads of time reading a six-book fantasy series and was upset I didn't commit to doing this (or even tried to argue me out of wanting to read or do something else).
She wanted to talk about these books, so why couldn't I just read them? I was "wrong" to simply want something else and had to justify my choices.
She'd enjoyed them, and it was like I wasn't a separate person.
And it was very one-sided as if I wanted to watch a (say) thriller movie over one she wanted she'd just negate that suggestion.
Same with food, drink, etc. It upset me as I could see she was often capable of compromise in a group (with bossier people!) but 1-1 with me she didn't feel the need.
(Realistically the only person you can expect to prioritise your tastes is yourself, your partner or immediate family..and even so not necessarily!
If I want to do exactly what I want to all weekend as I'm quite rigid myself...I know I need to stay solo and any company is a bonus).
It was ok when we lived in the same town and could quickly and spontaneously catch up after work but for longer visits it just got exhausting...
Unfortunately it's not very easy (or indeed appropriate) for others to try to manage this in an adult friendship.
Ok in a group but 1-1 it was too intense and hard to manage, along with the stresses of normal life.
I felt like I was having to jolly her along most of the time and she regularly would come up with "as your friend" style statements about how I "should" be behaving.
Which isn't what a friendship should be (she had stable supportive parents and a good job and home so it wasn't like she was in a vulnerable position).
Maybe I should have explained to her more, but I was fairly young and not really in a good position to do so
(And she'd have some "logical" argument ready to use on me).
I have a young relative where autism has been formally diagnosed, and a lot of effort teaching her spending time with other people doesn't mean getting her way 100% of the time, she needs to give them some space and respect their feelings and choices.
Obviously it's not great if people are lonely due to rigid behaviour... but some compromise does have to be made.
Especially if there's a big ask like expecting people to travel down solo for 3 days.
(I'd say if you know you're rigid and are self-aware, you're probably fine though 🙂)
