How Infidelity Affects Children - Helping Kids Cope with the Grief

Infidelity can have a huge effect on children, even if you think they don't know what is going on.  They are very good at detecting a change in parents' relationships. They will worry about what is going on and may even think it could be their fault.  It can affect their mood, their school work and many other aspects of life. It is important to be alert to the signs we have pointed out below and help them deal with the grief which can be caused by any infidelity in their family.

Sometimes couples slip into a situation of taking each other for granted, and a new relationship develops without them having had any intention of letting it happen.  Others just can't resist the thrill of the chase and the excitement of a new relationship and some are serial offenders.  Sometimes affairs may go undetected for years by the partner and children, but once the affair is out in the open it can have a devastating effect on the children. 

Adults may get into these situations and end up having an affair without considering the enormous consequences and the trauma to their kids.

Parents like to pretend to themselves that they have hidden the atmosphere between them from the children, but children are very sensitive and even if they don't know about the affair will often detect that something has changed and there is an atmosphere. 

If children get to know about an affair, or even if the parents think they have shielded them from the information but they sense something is up, it can very stressful for them.
If they don't know what's up, they might imagine all kinds of things or think that the atmosphere is somehow their fault.  If they do know, then they will be worrying about whether or not their parents are about to get divorced and they will lose one of them. 

There can even be situations where the child knows about the affair but the partner doesn't.  Maybe a school friend has seen the parent with their new boyfriend or girlfriend and told the child.  Imagine the stress that could cause a child.  They might even be bullied by other kids who have seen the child's parent with someone else. 

Parents should always be alert for any of the symptoms below in a child and try to get to the bottom of what is causing the upset.  Kids cope with grief well if they are kept in the loop.  The worst thing is leaving them wondering what is going on. 

How Infidelity Might Affect Children - Symptoms You May Observe

Teachers are often the ones who notice that something is wrong when a child's schoolwork starts to suffer. 

Other symptoms of stress and grief children may suffer could include:

  • Lack of concentration
  • Anxiety about the future
  • Poor appetite
  • Difficulty in getting to sleep
  • Bad behaviour at school and/or at home
  • Isolating themselves in their bedrooms
  • Reluctance to go outside
  • Faking illness to miss school
  • Refusing to talk to parents
  • Mood changes

Many teachers wish that parents would stay together for the children's sake at least until the school exams are over or they are older.  Others believe that living in a household where the parents are no longer getting along is a worse scenario. 

Every situation is different and it's impossible to generalise. Either way, the above are all symptoms of grieving, where a child is worried that they are going to lose a parent, or have already lost them if they have moved out of the house. 

If the child knows about the infidelity, they are likely to feel betrayed by that parent and may lose respect for them.  This can lead to problems of discipline from that parent, arguments and bad behaviour aimed at the parent who had the affair.  It can take a long time to regain that respect. 

During my years as a health visitor I met many families and many teenagers, who talked to me about the difficulties they faced when a mother or father was unfaithful.  

Helping Children Deal with Marital Infidelity

Here are some ways to help the children during these difficult times:

  • Be honest and let them know what is happening.  Not knowing the cause of the atmosphere can be worse and more frightening.
  • Give them as much of your time as possible.
  • Talk over their anxiety about the future and reassure them.
  • Make sure they know it is not their fault.
  • Make sure they know both parents still love them.
  • Encourage them to confide and get help from an aunt, grandparent or close family friend.
  • Try to keep up a good relationship with the extended family so that the children don't lose contact with the partner's relatives. 
  • Let their school know what is going on with their lives.
  • If needed seek counseling for the children and/or yourselves. 
  • Understand that what you and your children are dealing with is grief.
