Marriage week may sound cheesier than a Camembert, but the idea of couples taking time to pause and reflect on the state of their relationship is not a bad one.
Although most people think they know what marriage is about, we clearly don't have it sussed – the UK has one of the highest divorce rates in the EU.
The truth is that marriage takes work - if it was all about routine and comfort at a steady pace, there wouldn't be quite so many break-ups. But what are the chief causes for trouble in a marriage?
HuffPost UK Lifestyle spoke to three relationship experts and it seems there is only one clear winner: lack of communication.
"It's the problem I hear the most," says Christine Northam, counsellor for Relate, who provide counselling support.
Michael Kallenbach, couples counselor and HuffPost UK blogger agrees. "People in relationships often don't manage to communicate well and this can lead to misunderstandings and assumptions, which are often wrong."
Very often, Northam says, couples attribute a lot of other problems to this. So they'll say 'she doesn't listen to me, he doesn't talk to me' but it's actually a banner headline for other stuff.
"An example would be a couple who have a young baby and they are rowing a lot saying they can't communicate. They haven't realised there is a huge amount of pressure on them – they've got a baby, new roles, and need to work out how they co-operate and how they cope with finances. He might play golf and she might do yoga, and they've had to give these things up.
"You can express your anger which is projection, but it's whether you can say how you truly feel, such as 'I feel sad about not being able to do the things I used to'. The couple might say they can't communicate but it's all about the new baby."
Although it can be about the big stuff (illness, having a new baby, losing your job), Kallenbach believes that very often, conflict arises because of the small stuff.
"It can be things that might seem very small or insignificant, such as emptying the dishwasher or taking out the rubbish to the bins regularly," he says. "But the small things can add up and become big troublesome issues in a relationship where two people are living together.
"It can be a good idea to sit down with your partner or spouse, say once a week and talk about what's bothering you and discuss it in a rational and reasonable way. That certainly is a way of communicating rather than brushing it under the carpet, allowing it to fester."
