There is a big difference between a person occasionally viewing pornography with the knowledge and even involvement of their partner to a full-blown betrayal and using adult websites to start affairs with other people.

Like many problems, it can start innocently at first, with a person visiting sexually titillating sites perhaps out of boredom or a seeking escapism but then it can escalate to other behaviours, such as directly communicating with other people online and over time can become addictive and harmful.

ASK THE EXPERT: QI have been married 10 years and we have four children aged 9, 7, 6 and 4.

Recently, I discovered that my husband has been using adult chat rooms online and seems to have been communicating in sexually explicit ways with other people.

To continue with this process you may wish to seek marriage counselling ( relationshipsireland.com, accord.ie).

There is a good chance of success for the two of you, if your husband accepts responsibility for what he has done and if the two of you are willing to work hard on improving your marriage.

We set ourselves the challenge of trying as many as we could over the course of six weeks.

We have been on many dates and our phone has been pinging with notifications non-stop (trying to keep conversations going with lots of different men is actually quite the commitment – some dating apps are high-maintenance.) All the apps allow you to search for men, women or both, with all of them available on i OS devices, most on Android and some for Windows Phone, too. Tinder: Free Possibly the best-known dating app of them all, Tinder is most people’s first port-of-call when entering the world of dating apps.

Take some time out together You can also take action at home to improve your marriage on a daily basis.

For example you can prioritise a daily talking time with your husband when you share how each of you are doing.

When I challenged him, he was embarrassed and then defensive saying it was just harmless flirting and that he had not gone over any line.

I still feel really unhappy about what he has done.

Improving the marriage The discovery of your husband’s online world is a crisis in your marriage but it can also represent an opportunity.
