I basically got pissed off by this guy last week and blocked him everywhere, he's basically confused and is like telling whoever is in mutual to figure out why he even sent me a message on Facebook etc.

Have you?

Yes, a couple of days ago for lying to me.

Yes, weeks ago. Too many ********s.

I've tried but I just can't throw them away, no matter how bad they treat me.

Yes, for a few months now, they used to be close friends of mine, too much ********

yes

And it was my best friend

nnn;

Yes. Some people were harder to cut out that others. It really doesn't feel good when its someone you were close to. I had a situation recently with a person I had been friends with for 4 years who started getting really frustrated with me because I wouldn't answer her back on Facebook when she wanted me to and it just became really annoying/frustrating, especially when she told me how I should be recovering from my rough year with panic attacks and anxiety. I just came to the conclusion that no matter how long i had been friends with her, she wasn't understanding what was going on with me and sadly needed to be dropped so that I would be able to take care of myself without the negative interruptions. I got told that I was being selfish but only you know your emotions and what your body and mind needs to stay well.

This

All the time.

Cut my brother out a few months back after he treated my mother like **** and stayed with his pregnancy-faking girlfriend.

yeah a couple of disgusting, vile, toxic low-lives.
I can forgive a lot to a certain point but once they cross a certain line, I cut them out of my life and they're never coming back. I hold grudges forever.

more than once actually

yes, my ex best friend.

All the time, I actually wish I spent more time trying to talk out problems than just wordlessly ditching people without giving them a second shot

No; it's really hard for me to completely cut someone out.\

I'd just hate them secretly.

No, it's kind of hard to do.

If I don't really want to be around someone anymore, I usually just try to avoid them and eventually life will cause them to fade away. But that doesn't happen much since I rarely dislike someone enough to go out of my way to avoid them.

The whole concept of "cutting someone out" is petty, to be honest. I believe most conflicts can be solved by compromise and talking things out.
