A truly fantastic update.
I really hope you find a replacement nanny asap, but the boundaries you have put in, in the interim are great.
It is all slowly coming together for you but clearly your clarity is growing everyday.
I agree with every word of @RandomMess eloquent post.
I would like to add inelegantly that your husband reads as a POMPOUS, SELF ABSORBED, DULL, SELFISH, CLASS A PRICK.
I can only imagine that his selfish dismissal of you as a new mother, ENORMOUSLY contributed to your MH issues, if not caused it.
I commend you hugely for refusing to be patronised any longer by him.
He has assigned a role to you that suits his narrative and ego, so you can indeed expect him to push back against you now seeing him for who he is.
He is NOT a good man.
He is an appalling husband.
I'm really glad to read your thoughts on love.
Loving someone is not always a good thing.
Loving a person can be hugely disadvantageous when that person doesn't love you back and is happy to use your love against you.
Self preservation is a hugely important life skill to develop as is the ability to realise sometimes some people are just not good for us.
Your daughter is so lucky to have such a wonderful insightful, strong mother.
I know you have a very bright future ahead of you.
Keep posting updates when you feel able to.
They are most inspirational.
