While there may be truth in what she says in terms of many women putting a lot of their energy into one person, a dating expert has said there are pros and cons to the process. It may sound like a good idea, but there’s also potential for dating burnout.

Relationship expert and dating coach James Preece, author at , explained: "This is why balance is key and why the rule of three is so important. Dating three people at once is considered the sweet spot.

"It provides variety, fun and flexibility without the emotional exhaustion and pressure of juggling too many contacts. With three connections, you’re less likely to fixate on one person too early, or feel pressured to settle.

"Think of it like a job - you wouldn’t go to an interview and stop your job search. Dating various people, but within a small circle, gives you the opportunity to explore different personalities, lifestyles and interests without committing too soon.

"Having too large a roster can make it hard to focus on the person in front of you, and means you have to move from one date to another without giving them enough time or a fair chance. You'll be going on one date while thinking about the other people you have coming up, and perhaps you might not put enough effort into taking the time to get to know the individual in front of you as they are easily replaced.

"This can make it feel like a full time job, and it’s no wonder people begin to feel drained and even resent the process."

As well as this, he noted too much roster dating can often lead to frustration. This is caused by having too many people to interact with, text, talk and date.

You could start to resent them if you are having to make too much effort to keep things going. If it was just one person, then you could have a break, but if there are several it can become too much like hard work. That’s another reason why it’s a good idea to limit your dating roster to three.

By doing this, according to the expert, you'll have enough options to keep progressing, without overwhelming yourself. Plus, it will allow you to spend enough time with each person, really assessing their compatibility to see if a real connection is there.

If one doesn’t work, and fizzles out, then and only then do you add someone else into the mix. That way, you’re able to keep things engaging and fresh without stretching yourself.
