Going to play devil's advocate for a moment.
Are you planning to use your MA to launch a career? If not, if money is tight then I can understand the objection.
I would never spend thousands or embark on a serious course of study without discussing it with my DH. I am mainly a SAHM (I freelance when I can) and his job is pretty full-on, involving a lot of evening and weekend work, so because it brings home the bacon, and keeps our 5 children fed & clothed it's fair to prioritize it.
That said DH is very happy to support my doing some study to help me get back to work, or to help me expand my horizons and knowledge. He will also bend over backwards to change his diary on those rare occasions I get an invite to a night out in London without him.
So I don't think the not wanting to spend money signing up to something without having discussed it is necessarily sinister.
The asking permission to have your life back, to go out, the list of chores, having diet, exercise and clothing determined and controlled, contents of fridge checked, list of chores, no choice in type of phone handset, being talked down to, being expected to have sex when not aroused, being penetrated under false petrences, not being allowed to take medication, attempts to impose pregnancy, being accountable every half hour, not being allowed basic dignity or privacy, all is!
I am sorry if I have been a bit full-on MrsHW and I know you will baulk at this but you are being denied basic freedoms and human rights, enshrined by law. It's like a form of slavery.
You are a human being with equal dignity and worth and you deserve the same rights to happiness, love and respect as everyone else.
You have every right to choose what food you want to eat and whether or not you want to have a baby. Whatever else, just keep that in mind.
