I don't completely disagree with you cheating is the main problem. But do you think you can ever be in a relationship when you know you are sharing your partner with someone else. How do you even take that em seriously when they don't even know what they want. No matter how you look at double dating is a fools game sugarcoating it with if we understand ourselves we are good to go but I when you really start to feel genuine love for your partner you will not want to share
