I prefer to think of it as discriminating
I feel pretty selfish for pushing all my friends and family away. Just feel bad but don't know what else to do.
No. I'm a loner to protect myself from other vicious human beings. The ones that are wolves dressed in sheep's clothing.
Honestly I'm not sure why the two would necessarily correlate.
Being introverted is a personality trait so I don't how it is considered selfish to prefer spending time alone over and abundance of stimulating activity that doesn't suit them UNLESS they are married to an extrovert. Both can make sacrifices.
