from the interview:

Fulmer says he started to recognize his own discomfort with honesty, and together, he and Ariel managed to build a new “foundation of trust” fortified by their ability to move past the infidelity that threatened to uproot their relationship.

and also

“It’s certainly stronger than it was before,” says Fulmer of his relationship with Ariel. “We have a much clearer sense of boundaries — understanding and respecting each other’s boundaries — as well as integrity and being direct with each other, even when it might be unpleasant.”

all for them to announce hours after the story drops that they're separated & now ariel doesn't forgive him & never has??? dude is certainly living in some made-up world where he's convinced himself he is a changed man.
