Juno and relationships

Just finished watching Juno. Great movie. Sad. Deeply sad in a comforting sort of way. Being a man, there were some obvious ways in which I couldn't relate to Juno. But, subtly, I could see myself in her. Especially when she is dealing with the breakup of her babies adopted parents. I greatly could identify with her pain and confusion. She goes back home and asks her dad if true love is possible, if two people ever stay together. I have wondered that too. Many times. Sometimes I am fearful of getting into a relationship. Saves the pain of breaking up.
