Coleen Rooney says she hopes her husband has “learned” from his past mistakes and won’t get into “horrible situations” in the future.
The former England star’s wife said his past behavior was “not acceptable” but she would have to “live with it”.
The footballer has had previous brushes with both alcohol and other women.
In 2018, he was ordered to complete 100 hours of unpaid community work after admitting to drunk driving nearly three times the legal limit while driving another woman’s car after a night of partying.
Following the incident, the 35-year-old vowed to make his marriage work.
Speaking about the decision in a new Amazon documentary, Rooney, Coleen said: “When you make those decisions, you need to focus on what you want and not what else.
“Obviously, I listen to the people I care about: my mom and dad, and they’ve always given me a positive outlook on things and there’s nothing we can’t deal with.
“Hopefully he has learned and doesn’t get into any of those horrible situations again.
“But it happened and I have to live with it and if I couldn’t handle it, I would have ended the relationship.”
He said they had “overcome” previous incidents that had occurred at a different stage in their lives.
“It’s not acceptable what he did, but it happened and that was at the stage of life we were in at the time, but we’ve moved on,” he said.
“I forgive him but it was not acceptable. If it comes up, we’ll talk about it like we’re doing now.
“I don’t have the anger I had at that moment.”
Coleen met Rooney when she was 12, as the pair went to the same school.
They started dating when they both turned 16 and have four children together: Kai Wayne, Klay Anthony, Kit Joseph and Cass Mac.
It comes as Coleen is embroiled in a bitter legal dispute with Rebekah Vardy, wife of Leicester City player Jamie Vardy.
Coleen, 35, accused Ms Vardy, 39, in an October 2019 Twitter post of leaking stories about her private life after a months-long “sting operation”, earning her the nickname “ Wagatha Christie.
