@Jessa85 Well done! Finding your rage and opening your eyes.
All best for your meetings.
Remember - you are married, so start working with the premise that everything is JOINTLY owned. Including both your pensions, both sets of savings, investments, property, etc etc. Do not believe any 'this is MINE' nonsense.
A good solicitor will keep this top of your mind. I wonder if the courts can require full disclosure of earnings & assets, etc? I don't know but of course solicitor will!
Be careful about alerting him to you planning something. He sounds very unaware, but carry on as usual, while discreetly making your plans.
Copy / print everything relevant and have copies kept separately, maybe in your work locker, in case.
Although you both work, you'll be able to show you have all the childcare duties, because you're not as busy and important as he is ...
