If being together is more comfortable, why might one choose to be alone? Part 3 in a serial essay about solitude
In a relationship with another human being, do you together become more like the grander society? In the context of all human beings, can one become a more unique human being by remaining alone? The more humans one relates with the more they become like the average of all humans. 
But I don’t think it has to be this way. You can still be unique with a partner. 
Here, I find my ego again. Define ego. I don’t want to get deeper in a relationship with a partner because I fear losing my ego. 
I am reminded of an advertisement I saw on a pouch of loose-leaf tea, “Be in harmony with the flow of life.”
I am holding on too tight to my ego. I am resisting, as my girlfriend said. I am holding on to my ego because I want to be somebody. I want to make something of myself. Because I want to be loved. I don’t know why exactly. 
This seems like a waste of energy. If I just woke up each morning and went with the flow of life, I would have more energy.
