Here are two propositions:

1. My family intrudes on my personal decisions.
2. My boyfriend has an anger problem.

It seems quite possible that BOTH of these propositions are true.

Therefore, even as you resent and resist your family's intrusions, ALSO support, encourage, and insist upon treatment of his anger.

No matter what the cause, no matter how difficult your family may be, it is not acceptable, in my view, to take things out on you by carrying anger, and giving silent treatments, for the rest of the day and even into the next day(s).
