The content he's consuming is worrying, but that subjective so I'll set that aside for now.
Recently, he’s planning to ditch his 9-5 to get into streaming.
If you are a couple in a committed long term relationship, these kind of decisions need to be decided and agreed on together, not unilaterally.
But when I question how he is going to do his fair share of responsibilities if he gets nothing from streaming, he suggests me being the breadwinner until he makes it big.
Again, you would have to consent to this. He can't just decide for you. Any change in career/income path like this even for a reasonable new direction should have a solid plan. That plan should be enumerated with clear milestone targets and dates and not "until he makes it big".
This is the same man who said men paying for women’s education is a dumb move because she would end up leaving him in the end.
All of us choose our mates based upon our own personal criteria. Personally were I a woman, this misogynistic statement right here would have been enough to disqualify him from being anyone I would want to be in a relationship with.
Are you citing something specific, as in a toolset that has been leaked that the government is known to use with what it can retrieve or do you mean theoretically? I mean, sure, if an organization went to the extremes and desoldered the NVRAM from the phone and dumped the contents from an external reader they could likely get much more than fragments.
