Noting how generational trauma can "haunt" a person, Macaulay added that he's pleased with how his fatherhood journey turned out.
"I'm proud of myself," he continued, "that I can provide for my family in that kind of way."
And the actor credits much of his parenting style to Brenda, who he started dating in 2017 after the two costarred in Changeland.
"Brenda is such a good mother and she makes me want to be a better father, a better person," he added. "I see how good she is and I see how happy our kids are."
As for where Macaulay and his own father stand today? The pair are still estranged.
“I haven't spoken to him in about 30-something years," he shared during a March episode of Sibling Revelry. “He deserves it, too."
