Asami wouldn't attack her boyfriend. Mako is gonna be lucky she still considers him anything at this point...but Asami is a civilized woman who wouldn't write off Mako for being a dumb asshole. But Korra was in more of the wrong in Asami's mind. Hard to say.

Hell yeah. Asami is not fucking around. Honesty is important to her. Mako owned up, good but he needs to own up to his brother. Family is very important.
