For the majority of my life, due to intense various trauma throughout my life, I felt like I needed to have someone in order to be happy. It usually ended with more trauma and a lower depth of depression.
Now, after years of therapy and staying by myself, I can proudly say that I don't need anyone. Do I want someone? Yes. It would be nice to:
Cuddle on those rainy days/nights(or all the cuddles all the times)
Pick out what my girl is wearing for the day and seeing her smile with happiness
Brush her hair while she sits at my feet
Cut up her steak and feed it to her
Wash her hair in the bath
There's just so many things, more than I have time to list(at work) that I want someone to emotionally pamper. But, I don't need it to survive or to be happy in life. And that knowledge makes me happier than I have been in my entire life.
