I have a bit of a problem with this advice! Quite honestly if you are in a relationship you should not be entertaining meeting secretly with another person and exploring love -v- lust! Too many people end up in my office because they have not focused on their relationship. Couples stop communicating, stop paying one another attention and stop showing an interest in one another. This is what you call "working at your relationship". If you don't want to do it end your relationship before looking for another love interest.
We tend to think we're immune to falling in love with more than one person, but roughly one quarter of Brits say they've fallen for two people at the same time.The human heart is a wonderfully generous organ (yes, it's not the only one) and if you're a warm, open person who adores meeting new people, you could imagine yourself in love with ten people at once if you let yourself.We've all got the potential. What stops us is commitment to the relationship we're already in and time and energy
