I'm going to block a long time friend on a social media platform.
Are you really going to cut out someone you knew for a long time like that?
Yea, I don't care about them anymore because of an argument we had.
Sometimes friends can go through things but it is good to try to work things out so that your friendship can be repaired. You would miss your friend if you guys never made up.
It would just be easier not to see them.
But eventually you will miss them and regret doing that. Give talking a chance. You never know how it will end up.
