Buxton, also who wrote a book on the topic -- "The Other Side of the Closet" -- said she wished Isay had more support, but she disagreed with keeping their children in the dark.
"Family secrets are toxic and connote shame," she responded in a letter to the editor that was never published. "Most important is the anger children express when they find out about their gay dad or lesbian mom, anger that their parents didn't trust them enough to share the truth."
Isay's husband was leading a gay life, and Buxton said the children could have found out. "That would have been a disaster," she said.
She recommends that parents distinguish between "privacy" -- a family matter -- and a dark secret. "If it's private, they own it."
But, she warned, children always "know what's going on."
Such was the case with Dr. Loren Olson's daughters. Now 68, he came out to his wife and left the home when his daughters were 9 and 13. The couple didn't tell the children for three years, thinking the girls would better understand sexuality.
He said his wife considered staying in the marriage. "I didn't think that was workable," said Olson, a semi-retired Nebraska psychiatrist and author of "Finally Out: Letting Go of Living Straight"
"It was a side of myself I had discovered and I was not able to put it away again. If I continued to live a lie, I was afraid I would put myself in embarrassing, shameful or an even illegal situation and bring greater damage to the family -- I knew I couldn't put the gay away."'
When their daughters were 12 and 16, Olson and his ex-wife revealed the truth.
"We planned a big event and tried to make it a nice day and minimize the pain," he said. "I said, 'I have something to tell you,' and they said, 'Oh, Dad, we knew that -- let's eat!"
"Kids are remarkably perceptive," said Olson. "They know something is going on -- not the details -- but there is obviously unspoken language in families."
Today, he has a good relationship with both daughters and his wife, who has remarried. But he acknowledges the pain she went through.
"It isn't like most of us really deceived our wives, as much as we deceived ourselves," said Olson. "But a lot of women are angry and think they were duped and exploded."
That was not the case with Michelle DeShazo, a 30-year-old education student from Utah, who learned her husband of nine years was gay just three months ago.
"I didn't know anything was wrong," she said. "But I had my suspicions. When he came out, I felt like something had always been wrong with our sexual relationship. It wasn't as intimate as I thought it should be."
But unlike most other women, DeShazo has decided to stay in the relationship and allow him to pursue same-sex relationships.
"I am just going to accept him for what he is … We are going to work it out and have a polyamorous relationship, first his side, then mine."
DeShazo said they will eventually tell the children, "but I don't know when." She said she loves and trusts her husband "absolutely, 100 percent."
But Buxton said she was filled with anger when she learned her husband had kept a secret for 24 years.
She noticed subtle things like his change in wardrobe and even the children saw signs.
"Whenever we went into the living room we were never in a fight or a clinch," she said. "Kids can sense the lack of chemistry."
When he came finally came out, Buxton, devastated.
"I had to figure out what is homosexuality and how would it affected my life and what did it mean for my kids to be children of a gay man," she said. "Once I accepted it, I could rebuild my moral compass."
Part of rebuilding was vowing that no other spouse would share the same pain. In 1984 at the height of the AIDS crisis, she accepted an invitation to speak at a gay father's group in San Francisco to men who had no idea what their wives had experiences.
"We gave a talk to a panel of 50 men and tears were rolling down their faces," she said. "We were not their wives, so they listened."
Buxton wrote a book and became an advocate for gay rights, joining PFLAG and starting a support group in 1991. By 2001, the Straight Spouse Network became an independent organization and today has 54 support groups in 11 countries.
She also found love again and remarried, though her husband died just seven months ago. Today she is a supporter of equal rights for gay, lesbian, bisexual and transgender Americans.
"I almost left my Catholic faith because of the Vatican view of homosexuality," said Buxton. "But I was not going to give them the power to take away my faith."
