I ghosted my dad
Why would you ghost your dad?
Because I don't want to keep getting into conflicts with him.
You shouldn't be ghosting a parent just because you don't want to get into a conflict with them. Going out of your way to talk about an issue shows a sign of maturity that comes with age and adulthood.
It's not like he will listen to me.
In non-abusive situations, ghosting your parents is rude. If you don't want to keep having conflicts, you could work on finding some topics that you both enjoy talking about so you can avoid the ones that lead to conflict.
