I’m totally the opposite. If you didn’t sleep with my twin or stab my grandmother we can be cool. Relationships run their course and the time for the romantic part of it has ended. Just because I don’t marry someone doesn’t mean they lose their significance. Yes, it can be an issue with the next relationship but there’s always gonna be one. I don’t throw away friends I’ve had for years in exchange for someone with no time in. It’s not the best for the new person but you learn very quickly how secure one is. This approach isn’t the best for everyone. It only works if you’re just as fine being single as you are in a relationship.
