Ghosting someone feels awesome.
I don't know if you are being sarcastic or sincere about ghosting.
I'm serious. Ghosting feels great. Moving on from an uncomfortable situation is very freeing.
While you are under no obligation to continue on in an uncomfortable situation, it is wrong to just ghost someone and then take pleasure in doing so. If someone's behavior indicates you that you do not want to socialize with that person, you should tell them outright rather than ignore them and hope that they get the hint. You'd be doing them a favor: people should be aware when their behavior negatively affects others so they can have the opportunity to change.
God damn, I still feel like it's fine that I ghosted them.
Ghosting is not a sustainable coping strategy in the long run. You can't just ghost you spouse, boss, relatives, co-workers, and others every time things get uncomfortable. You should seek counseling to help you develop a more versatile approach.
