Old friends for sale

That snooker "friend" i have, best not to use names so we'll call him "nitwit", we have been chatting practically daily on whatsapp for years now, but we had our issues in the past.

In many aspects he's not the worst dude but there are a few things you can not do if he considers you a 'friend'.
You cannot say 'NO', period, he has some kinda of brain shortcut that goes into overdrive when that word is used.

Example:
He once asked me, after a hard workday, if i wanted to come over the next day to play for few hours.
I answered i was kinda looking forward for some rest and relaxed time instead.

Big mistake, the brain shortcut made him start flaming and stuff, which resulted in him not speaking for a few weeks.
He didn't 'defriend' me on that occasion but he did before.
Few weeks later i noticed he was doing a crowdfunding and it was only after i made a donation to that that he started talking to me again.

He plays in the disabled snooker tour btw, WDBS.

Anyway, with the recent 3 heart attacks i had his chat responses became even weirder, not showing any empathy at all, and kinda seeing it as a competition.

Like when i told him about the experience i just had his reponses were like:
"LOL i had 7 of those before"
'Stop thinking about the past",
"I live in the future",
"I'm a positive person"

Not really something you want to hear when your in a hospital bed and when you are on heart monitoring.

He also didn't understand my decision to cancel playing in DMT open March 29-April 1, while it was clear i would not be allowed to drive yet during that weekend (in Belgium you are legally forbidden to drive with a car for 4 weeks after a heart issue) and i will probably still be in hospital when the DMT open tournament starts, so how could i possibly play there?

Anyway, i was already kinda annoyed with some of the things he had said in the last few days, while i was watching a movie and my wife, who stayed home from work to make sure i was ok, when he was doing a facebook live session and then he asked if he could call to talk about a computer problem.

I thought that was a bad idea, as i was recovering from the hospital sessions still, i was trying to stay away from smoking and i still had a clogged artery, besides i thought my wife, who is protective of me wouldn't like me to listen to other people's problems.
After all, she was still relieved i didn't die during those heart attacks few days ago.

Sooo i used the 'NO' word, bad idea i guess, the brain shortcut happend again, the flaming responses started and nothing i said could change anything.

Late tonight i had to go see my doctor, who has just been on vacation, to bring him up to speed on all that happend, so it was pretty late when i got home again, after 9 pm, and next i noticed was he already 'defriended' me again on facebook.

This of course made me very stressfull - i'm not good at handling conflicts - and it kept me up all night, not good to be so stressed when you just had heart surgery few days before.

Anyway that's when i understood that this is not a good person to have in my life, he has no respect or empathy for anyone else - including friends, family - he just uses people when he needs them and then soon forgets all the favors anyone ever done for him.

That's when i sent him one final message, making it clear that i want nothing to do with him ever again, and then i blocked him in any way i can think off, it is actually very evil to purposely defriend someone and make him stressed knowing that person just had several heart attacks and who just quit smoking, Twisted and borderline illegal.
