Well, I shouldn't probably even worry about this anymore, considering I'm above taking things like this personally but I still feel like I have to at least ask advice about this

How do I put this? There is an asshole that I have been watching for quite some time (not going to mention who). At one point I was friends with this person and would usually chat with them, however now as time has passed, this person has grown a toxic personality of self loathing and constant bitching about how his/hers life is horrible, and how he/she wants to just leave (for the 15th fucking time). Not only this, but usually when I comment on any of their new artwork submissions or journal entries, this person always responds rather disgustingly. And not just only me, but usually when others try commenting on stuff, such as giving their opinion on the subject of this particular person's journal, he/she always, ALWAYS responds negatively and just blocks them, or tries to warn them that he's/she's going to block them.

Now I've grown over the years to be a very blunt person: I say whatever I want to say, but I'm also sensible about what I say and whether or not it can be interpreted as offensive or not. With this knowledge, I recently commented on this person's submission, which really was just a silly little topic on something. Shortly after they responded with a rather heated comment, to which I try and explain why I made said comment, but only for them to come back at me and say the most hurtful thing towards me. Then soon afterwards deleted the whole slew of comments so they aren't shown as the "badguy."

I've grown sick and tired of seeing this person's shitty attitude, and I wish to unwatch them, however this is where I'm having personal conflict on this. Should I do this? should I just simply stop watching this person and just be done with them and unwatch/block, or what?
