9. Financial independence. You do not have to ever pay for anyone else. You make your own money. So, spend your money the way you want. No joint bank accounts, no one telling you how to spend your money and no one asking you where your money went.
10. Emotional independence. This is probably the most liberating piece of all. Partners are not always supportive of our emotions. They take our emotions personally, they don't understand them or they don't support what we are feeling. Singles don't have to explain why they feel happy, sad, angry, tired, moody, crabby or frustrated to anyone. Feel free to feel every emotion you have inside of you and not have to respond to anyone else about them.
Some of these things sound downright selfish. But, the irony of it is that these seemingly selfish concepts might actually benefit our relationships. We might end up feeling better about ourselves in the long run, which in the end is key for long term happiness.
