I find that wine makes me a very deep thinker, so I'll assume it's the same for you.
When we are free of the alcohol we KOKO (keep on keeping on)- as in just get on with things.
However, childhood abuse has a lifetime legacy - there is no escaping the fact that when you were most vulnerable (dependent), you were most exploitable.
Reconciling your (now) adult understanding of parenting, with your childhood experiences, is incredibly difficult and painful.
Can I suggest that your partner is not sufficiently trained or insightful to help?
There are people out there who are trained and insightful. Forget what anyone has to say about getting counselling - it isn't the preserve of Americans. It actually does help you find some assertiveness and assurance in yourself.
I'm the first to stand up and say 'yes, I have a weekly counselling appointment'. Anyone who knows my current situation (divorce) is very accepting of that. Anyone who is judgmental is called the 'Mother Component'. She thinks it's a little too self-indulgent.
I'm learning to value what I think, need, do and say. Less so for others.
So, I'd recommend it you consider that as a way forward.
KOKO and take care.
