Feeling is not everything

Feeling used to be all it takes for two to become a pair. I was having this naive little concept back then. As I grow older, it isn't that simple anymore. All other factors came in the way: character, life view and goals, background, situations etc. Have I become more realistic? Experiences have taught me that. What is the point of getting together when you know it won't work out in the long run? Is this also a way to protect ourselves from getting hurt again? I didn't regret my past a single bit, at least I truly felt happy before it crashes down. But that is enough. It is a phase in life i will never forget and will never ever, repeat.
