Would you rather prefer getting cheated on or asked for an open relationship?

Anonymous
Scenario: Your partner either fantasizes about other people or is starting to like someone else.

Would you rather:
a) get cheated on... they didn't want to tell you because they thought ''ignorance is bless'' but then you find out later on
b) get asked for an open relationship (they tell you straight out ''I want to sleep with others'' or ''I'm starting to like someone else, I would like an open relationship'')

Between those two options (both obviously will hurt) which one would you prefer? Pick one.
