New Girl

I've been watching the TV series "New Girl" and I'm learning so much about relationships or life decisions in general. It seems people break up when they realise their partner is not who they want to spend their life with. It doesn't matter if they like them as a person, doesn't matter if they're good looking, nice, warm, friendly, smart or whatever, because this brilliant, lovely person is just not the one. You want to break up so that you can be single and find someone who's more right for you. Interesting perspective. It would require forming an opinion or having a general idea of what you want in life and then knowing that this person does not fit into that ideal. What if you don't know what you want in life?
