Should I stay after they cheated?

You can stay after someone cheats, and some couples do come through it, but only when the person who strayed is completely honest and willing to do slow, real repair. The harder question after 60 is whether you would be staying for them, or staying because you are afraid of what leaving would cost.

Those are two different decisions. It helps to make them one at a time.

Why does this feel even harder later in life?

Take Joan, 66. She and Ray, 71, have been together five years. They kept their own homes, which suits them both, and spend most weekends together. Ray drives her to her cardiology appointments. Her grandchildren call him Grandpa Ray. Last month Joan saw a message on his tablet from a woman in his walking club, and over a hard evening it came out that it had been going on since spring.

Joan’s first thought was not about the affair. It was: “Who will take me to my appointments?” Her second was: “My daughter never liked him. She’ll say she told me so.” Her third, at two in the morning, was: “Who else is going to want me at 66?”

None of that makes her shallow. Later in life, a partner is often tied into your health, your routines and your family in ways that make the betrayal feel bigger and leaving feel impossible.

It may also help to know this is not rare in your generation. University of Utah sociologist Nicholas Wolfinger, analyzing General Social Survey data, found that in 2016, 20% of Americans over 55 reported sex outside their marriage, compared with 14% of younger adults.1 The highest rates were among people born between 1940 and 1959.1 You are not the only person your age sitting with this.

How do you separate the facts from the fear?

When something like this happens, four things blur together. Try writing them down separately.

• What happened. Only facts. “He saw her for about six months. He says it’s over.”
• The reading. What you think it means. “He never loved me.”
• The fear. What it touches. “I’ll end up alone and nobody will help me.”
• The next step. One thing you can do. “Ask him to tell me the whole story, start to finish, on Saturday.”

The reading may or may not be true. Nobody can see inside Ray’s head, including Joan. What she can see is how he behaves from here.

What makes staying more likely to work?

Research on couples who stay after infidelity is mostly about married couples in therapy, and mostly about people younger than you. Still, it offers some hope. In a study by David Atkins and colleagues, 19 couples dealing with infidelity were part of a larger trial of 134 couples in marital therapy.2 They started out more distressed than the other couples. But couples whose affair came into the open before or during therapy improved more in satisfaction than couples who had no affair at all.2

The key words are “came into the open.” Repair tends to rest on things you can actually observe:

• The whole truth, told once and clearly, not drip-fed as you discover more.
• The other relationship ended, in a way you can see.
• Patience with your questions, for longer than they would like.
• Willingness to get help together, such as a couples counselor.

If you get defensiveness, blame or “why can’t you just let it go,” that is information too. It does not tell you what they feel. It tells you whether the repair is actually happening.

What about your health, and theirs?

Two things matter here.

First, your physical safety. Many STIs have no symptoms at all, and the CDC notes that the only way to know your status is to get tested.5 Ask your doctor for testing. It is a routine request, and you do not owe anyone an explanation beyond “my partner had another partner.”

Second, the strain itself. In a study of about 1,200 married adults aged 57 to 85, Michigan State sociologist Hui Liu found that a strained, critical marriage was linked to worse heart health, and that the link grew stronger with age, especially for women.3 That research was about marriage, not a betrayal in particular. But it is a reminder that staying in a relationship that stays painful is not a free choice either.

What if the real fear is being alone?

That fear deserves respect. The National Institute on Aging notes that loneliness and isolation are linked to heart disease, depression and cognitive decline, and that older adults with supportive social connections tend to be healthier.4

Notice the wording, though: social connections. A partner is one of them, not the only one. If the thought of losing Ray means losing every ride, every Sunday dinner and every voice in the house, the first job may be widening your circle, whatever you decide about him. A friend who can drive you to appointments, a neighbor you see each week, a group that meets every Tuesday. When those are in place, you can ask the real question with a clearer head.

As for your family, you do not need their vote. You may want one trusted person on your side, whether that is a son, a sister or an old friend, who will listen without deciding for you.

When is it time for more help?

If you are not sleeping, have stopped eating well, or feel low most days for more than a couple of weeks, please talk to your doctor or a licensed mental-health professional. Betrayal later in life can stir up old grief, and that is exactly what counselors are trained to help with. Seeing one is not a sign you are falling apart.

What the research does not tell us

• The therapy study was small (19 infidelity couples), involved married couples, and could not say what happens without counseling.2
• The survey figures describe trends, not why any one person strays or whether they will again.
• The heart-health study was correlational. It shows a link between a strained marriage and heart risk, not that one caused the other for everyone.
• None of this can tell you whether your partner is sorry. Only their actions over time can show you that.

What to do this week

• Tick the list above and notice which worries are carrying the most weight.
• Write out the four lines: what happened, your reading, your fear and one next step.
• Book an STI test with your doctor.
• Solve one practical worry on its own, like lining up a backup ride to your appointments.
• Tell one person you trust what happened.
• Give yourself time. You do not have to decide this week whether to stay.
