It can go on forever

 "There's a reason I said I'd be happy alone. It wasn't because I thought I'd be happy alone,  it was because I thought if I loved someone and then it fell apart, I might not make it. It's easier to be alone. Because, what if you learn that you need love... and then you don't have it? What if you like it? And lean on it? What if you shape your life around it... and then it falls apart? Can you even survive that kind of pain? Losing love is like organ damage, it's like dying... The only difference is that death ends. This? It can go one forever."
