A relationship expert has revealed the number one thing to keep an eye out for when considering how healthy your relationship is.

According to relationship expert, James Preece, thinking about what it might be like to date someone else is a major red flag.

“If you keep wondering what it might be like to date someone else then it’s time to get out,” he said. “While it’s fine to have the odd fantasy about a celebrity, if you keep looking around at other people all the time, then you have to question why.” he told Daily Mail.

If you’re constantly wondering about what the fuss over Tinder is about, are envious of your single friends, or you’ve been eyeing out others, then things aren’t looking good for your relationship, according to James.

‘All these are massive warning signs that something is wrong with your relationship,’ he said.

‘If you are thinking more and more about people that aren’t your partner, it’s almost always because you are bored. Once that starts to happen, the magic can quickly fade and you’ll stop putting in the effort to make things work.’

‘Nothing original or fun is happening so you begin to look elsewhere just for a bit of excitement,’ he added.

If you do want to save your relationship,  James suggests organising a regular date night with your partner, changing your regular routines up

‘Just remember, it’s better to get out of dead end relationship than stay with someone just for the sake of it,’ he added.
