I want to be a single parent by choice
Why do you want to be a single parent by choice?
I can't imagine being apart from my child.
While being a single parent is okay, it isn't something that you should want since a child should be able to experience the love of both of his or her parents while growing up. It's wrong to want to have a child all to yourself and deny the other parent from being involved. You should try to have a stable and lasting relationship with your partner before deciding to have a child.
My child needs love and care that can only be provided by me. Also, I have the right to have a kid if I want to.
It's not true that love can only be provided by you. A child needs both its mother and father in its life to take care of it. You are being selfish by denying that to the other parent.
