Background: my mother and I have had a very strained relationship this year. She has always been very controlling but this year I had a baby. My first. When I was pregnant and told her so, she gave me a short lecture on how hard parenting was and that she doubted my parenting ability as she believes I am too sensitive. She then went and got lots of baby stuff without telling me, buggy, changing mat, clothes. All second hand and of mixed quality. I asked her to let me know and check with me if she was going to get more things and to not buy any more because I had things from my in laws and had got things already.
Today: she texted me 'do you want me to make your birthday cake, normally I would but I have to put brakes on now to check everything'. I pointed out that it sounded passive aggressive and now she says I hate her, am hostile and she is threatening to cut ties.
Am I being dense here or was that a subtle dig?
