On waking, I'd had a response to my text saying simply "Fine. Have a nice, stress free life then".
I'm not answering or engaging any further.
To those that think I've been harsh, you're entitled to your opinion, but you've not lived my life so you can't really comment. I've obviously left some things out to keep it unidentifiable but this was just one snippet of her entitlement, it certainly wasn't the only one, I've just ignored the other behaviour in order to stay friends. I wasn't prepared to do that anymore, and actually I never expected any of this.
I truly thought her response to my request of walking 7-15 minutes to mine (depending on route taken) would've been:
"Of course, no problem, anything to help, especially as you're driving my dd every week!" "Do you mind if she gets to yours before it's dark though?"
To which I would've replied "thanks for that I appreciate it! Of course she can, that's no problem, see her then!"
And it would've been done.
That's how I would've reacted to a request from a friend, and I think most people would agree with me there.
She caused the drama, not me.
Thanks to everyone for their support and opinions, for and against, as it's actually given me lots to think about and really cemented how I feel about what's happened and how I reacted, etc.
