When we hear of couples splitting up, there is always a sadness there.
We don't like seeing relationships end. We want couples who have been in love and built a life together to stick with each other through thick and thin. We all want relationships to work out because we know the pain when they don't.
So it will be interesting to see if Ronan and Yvonne Keating make their relationship work. Twelve years and three children -- surely that deserves a fight to make things better. But it's not that simple.
There is one exception to the above sentiment. We don't like seeing couple split up UNLESS one of them has been unfaithful for a long period of time.
Seven months is a long time, and this is seemingly how long Ronan Keating and the dancer Francine Cornell have been seeing each other.
This wasn't a one-night stand or a two-night fling.
It wasn't a few naughty texts or a drunken romp after a big night out.
This was a relationship. I know people who have met and got married in seven months. It's a long time -- especially in Ronan Keating's life.
He would have been with his lover since last October. He would have been thinking about her while he was spending time with his family at Christmas.
They would have been together during the time of Stephen Gately's death.
Throughout these personal times, Yvonne would have been there to share in his happiness and his pain. To support him, to help him and to love him.
So do we take the stance that she should not allow him back into the house, or do we want them to make it work?
The gut feeling of a lot of women out there is: Kick him to the kerb, Yvonne. He has shown you what he thinks of you, so let him go.
Women can see it as a weakness when they take back a cheating husband.
I, personally, don't think it's that simple.
Was Hilary Clinton weak? We all thought the wife of the president of America was going to leave her husband after the revelations that he had a relationship with the intern Monica Lewinsky.
But she surprised feminists around the world by sticking with him.
Now some might say it was political, and that it would be more beneficial if she stayed with him. Whatever her reason, she found strength from somewhere to defy her critics and stand by the man who humiliated her in front of the whole world.
I remember speaking to an American friend who was involved in politics.
I asked him why Hilary Clinton was so despised by so many Americans.
He says they will never forgive her for not leaving Bill Clinton.
On the other hand we have Elin Nordegren, the wife of Tiger Woods, who very quietly and in a dignified manner, put in for a divorce from the most successful sportsman in the world.
We had all wondered if this woman could turn a blind eye to numerous affairs throughout their marriage, and lie back and think of the dollars.
But no, she decided that infidelity was not something that can be part of their relationship and wanted out.
Let's not forget here that there are many, many women who live in the knowledge that their husbands have mistresses. I know one.
I find it upsetting, but she would rather her children have a father, and she have a husband (for 75pc of the time).
The French, as we know, see nothing wrong with husbands have a lover alongside a wife -- and it's not only the men who see nothing wrong with this.
Possibly the biggest mistake Ronan made was getting caught out. This relationship might have fizzled out and no one would have been the wiser.
Now, for Yvonne, she is going to have to make the most difficult decision of her life, as we the public look on.
Should she separate from the man she loves, the father of her children and her best friend, or should she forgive him and let him come back home?
Both difficult options, and I wouldn't like to be the one to have to make that choice.
