They can work if both people want the same thing. I think that is the key. Even if both people love each other, if they dont have the same ideal of a relationship, its not going to work.\nFor example, If both want a no strings attached thing, it works, if both want to get married, it works. But if you want to have a committed relationship while the other person likes you a lot,  but wants to keep his/her options opened, it wont work.\nIm not involved in one but I was once. They can be more intense than  an average relationship. Every meeting is special filled with passion and romance. The bad thing is you tend to feel like you need to take advantage of the time you have together and avoid talking about the problems you might have, which is bad for any relationship.\nThey also require you to invest more time and money than a regular relationship.\nIt can be very emotionally draining.
