The situationships hurt way more than the relationships.

It's worse when you don't date the guy. Because when you date a guy he shows you every single side of him so you can build up resentment for him and he can build up resentment for you, so that break up is kind of easy cause you may hate each other. When you know someone so well, you have all the data points to let you know all the things that you may hate, but when you don't have that information, it's so much harder because you start filling in the blanks for yourself.
