Have you been referred to psychotherapy but your GP because you have discussed your mental health anyway?
Or have you chosen to have therapy and found your own therapist?
This is important as there are so many different types of therapy.
What some of us are picking up from your posts is that you seem to backtrack to minimise what can be seen as abuse. You post one thing, then a few posts later say 'Oh not's not like that really.'
For example, you talk about being punished and having things withheld as a punishment. what do you do and what happens here?
It's hard to see how, in between marriages, you managed to successfully cope and bring up your daughters, yet now you can't manage to get yourself to bed on time.
I don't genuinely know how you can't manage your bedtime without being 'sent'.
Why at 40+ do you need your H to 'lie with you' and take you upstairs to bed?
But then confuse the whole bedtime issue by saying you also get sent there as a punishment.
If you were a child, and your parents did this, they would be told it was bad parenting. Bedrooms should be a place for relaxation and sleep - not a place associated with being naughty and a 'cell' to be sent to.
If your marriage can only function with you playing the role of a child and him as a parent, it's dysfunctional.
