I realize that I don't want to be in a relationship
Why don't you want to be in a relationship?
It's too much work.
Not everyone thrives in relationships. If you like being alone, that is totally fine.
I didn't say I liked it, I just said it's too much work.
Ah, my bad then! I can agree that relationships can be a lot of effort, and it's up to you in the end if you want to use up your energy. It's all okay to do whatever you want, because it is your life and your private life!
