My friend and I have been friends for many years, we have children close in age so usually arrange something a couple of times a month to take them out/meet up for a play date etc we also frequently meet without the children when we get the chance.
A few weeks ago she messaged me to say that she was going to book an activity day for herself and DC that weekend and would I like her to book us on too, I replied thanks for thinking of us but I simply didn't have the funds so we'd have to pass this time. She read my message and then I didn't hear from her for the next 2 weeks (we'd usually message every other day).
Yesterday we were supposed to meet with the kids at the local park but I had a migraine and it was making me sick so I text her to apologise that we wouldn't make it, again she's read my message, and subsequent messages, and ignored them all.
She does this pretty much every time Ive said I can't do something or had to cancel plans (which isn't that often but there's been a few times over the years) and I've called her out on it a couple of times but she just either ignores my question or makes out like she doesn't know what I'm on about. Fwiw she cancels plans etc as much as I do, life gets in the way things happen, but I'd never dream of giving her the silent treatment for it and I'm sick of it tbh.
Where do I go from here? I don't want to lose the friendship but I feel like every time she doesn't hear what she wants to hear she's spitting the dummy out the pram and I can't be bothered with the childishness.
