Since then, I found out that DM and DF have visited the area where I lived but gone home without telling me
whoah! after all that telling you you had to go and visit them?!
DF has always said she 'doesn't do emotions'
oh she does, doesn't she? all that crying, all that demanding hugs then thinking you her.
But she only does her own emotions. No one else's.
why does DM want to carry on hurting me? It's not like she particularly seems to enjoy seeing or hearing from me when I do meet up with her or talk to her, yet she always wants more
These are -her- issues. There are some very mixed up people who get married and have kids and then all that mixed-upness comes out onto the kids. It actually isn't to do with the kids, it's to do with the damaged person who can't or won't help curbing their behaviour. Sadly, the kids are the closest easy target for -their- issues.
It's not you. Nor your behaviour, nor your personality. It really is her.
It makes her recent behaviour all the more strange, because she's effectively taught me over the years that she doesn't care about my feelings but now she wonders why I don't tell her things or want to spend lots of time being close to her.
Cognitive Dissonance. She probably isn't -able- to see that the way she behaved means that you can't confide in her. Damaged people have a choice: seek help or stay damaged / get worse. Decades ago the help and knowledge simply wasn't there.
It was really hard seeing him get so emotional about the possibility of leaving the cats behind and thinking that that might have been a reason they never split up years ago. Is that mad? Or maybe he applied the same logic to us as his DC, he couldn't leave because he thought he wouldn't see us?
the cats are neither here nor there; on the scale of perspective, living your life in misery because of the cats isn't worth it. He could take them with him! The children is a harder thing. Women still get majority custody a lot of the time and I know at least one marriage where the man stayed because the mother was extraordinarily manipulative and convincing. It was the right decision because things would have been 100 times worse for the kids without him there.
But a lot of the time, it's simply very hard for an abused person to leave. If your father was conditioned by his own parents, then it might have been downright impossible.
People like your mum, who live in their own heavily-controlled world because they can't bear perceived-threats from outside, often struggle very hard indeed with children maturing and growing their own wings. They -have- to control everything around them for their own perceived-safety and you doing your own thing, not being controlled, is literally unbearable.
But as an adult you have to break away from a controlling parent like this, or live forever in her shadow. Her negative influence can last even beyond her death because the patterns of thought and interaction can remain for years after.
You are doing the right thing in breaking away, without any doubt. It comes at a heavy price tho in grief. Stay strong, there are people who understand and will support you
