What is the best thing about being single?
Having a life. I hear that ends quickly when you pick up a significant other.
The only reason your social life ends once you become attached is if you let it. A healthy relationship does not consist of clinging to each other at all times, passing up fun events, and going home retardedly early from parties. I spend plenty of time alone with my friends, and if my boyfriend were ever to complain, the relationship would end pretty quickly.
