I think I really dislike and do not want children.
Why don't you want children?
I just don't want to spend my time on something that will not bring me any joy.Also it's not my top priority right now.
Your life your rules. It's cool if you don't want to have kids.
I have to have kids, I have to keep the lineage.
You shouldn't allow yourself to be forced or guilted into having kids just to carry on the family line. The decision to have kids is a big one and should be taken seriously.
