No Asami still doesn't fully trust Mako, as is evident by her not wanting her and Mako under the same roof but she isn't heartless. If Mako needs to resolve some shit, he should but if anything that conversation should be done with all three of them because unless she witnesses the closing of the chapter that is their mistake, she will have more doubts. If she can fully bury the hatchet, it would make room for a fresh start between her and Mako. At the same time, Asami doesn't feel right beating a dead horse because it's going to keep the wound fresh and open. She wants to move on, Mako and Korra know they were wrong. Asami and Bolin are hurt, she wants to move on as they all should.

Awww Brittney...I miss her golden years.
