Quiddichcup It's absolutely not you that's at fault.
You had a normal situation and an abnormal reaction from your mother.
And now you're in the fallout from it, and I know what that's like.
Long story short, there was one five week period when PILs were upset with us. We were all due to be travelling on the same day. PILs were travelling to Devon, we were travelling to Dorset. PILs like an early start and left at 8am. We weren't in a hurry and decided to set off at 1pm.
They were travelling from their house and we were travelling from ours.
PIL's found out we had set off later than they had and all hell broke loose. Apparently we had deliberately not told them we were leaving later, had they known they would have met us for breakfast, we had planned this just to upset them, we should have been more thoughtful, how dare we do this to them?
The upset from this went on all through Christmas and New Year and through two weeks where DH and I had Norovirus and we were really ill.
PILs were ringing and ringing and ringing to shout at DH and so we could both rest and have some peace I turned the ring volume down on the phone.
A couple of hours later DH commented that they must have calmed down and I said I'd turned the ring volume off.
We'd only been married about a year and half by then, I wasn't so far down the rabbit hole with regards to their behaviour, and DH wasn't so far along in his acceptance of how they are.
So he was in a total panic, said I'd made it worse because if they'd called and couldn't get through they would be even more upset and angry now.
He turned the volume up and the phone was ringing in his hand.
It was FIL, who kicked off, screamed that we were selfish, ungrateful, disowned, disgusting people, that MIL was in tears, that he was sick of our behaviour, that we must apologise, that we were terrible, awful, stupid, we were users, we were liars, and he and MIL deserved better.
So I know what you mean when you say it's bad when you answer the phone and worse when you don't.
It took about eight more years for us to go NC, and that wasn't the first or the last time we had phone calls like that. They were a frequent thing, and they are exhausting, and they are designed to grind you down so that you know your place for next time, doubt yourself, and tow the line.
I think you know that too.
The other thing is, people like your mother and my PILs are not consistent. I said before that it's like living under siege and that what you do right one day is an example of everything you do wrong the next. You can't please these people, because even if you do exactly what they want, they're not happy and they will find a way to convince you that you're getting it wrong.
You're a good person Quiddich , your DD alone sounds like proof of that. Don't let them make you think otherwise.
This is your mother's fault and the people around her are enabling her to make you feel like this because it's easier for them. It's easier for them to blame you than stand up to her. It's easier for them to think you're in the wrong because then they don't have to change anything.
But it's not you, and it's not your fault.
