Firstly, i'll say that I'm finding it difficult to deal with having been lied to by my mum on multiple occasions, over years. It has affected my trust- I don't think it's that unreasonable for me to feel like that. I'm not in a theoretical situation here.
I did say to mum that, over the years, I've consistently said that both me and my sister should be involved in any discussions, so everyone knows what's going on. She agreed that I've done that. And here we are...
I've done a lot of reflecting on myself- not least as I have tried to understand what I could have done differently, and how that might have changed things. It eats away at you, you know?
