/cgl/ - Cosplay & EGL

I've been having second thoughts about my friend who I've been with for nearly a decade..

We got into anime/cosplay and things of the sort together at the same time/age and helped each other grow from it, we've had many a good times (and bad times but that comes with the good)

But lately I realize I only have fun with them at a con setting and when we specifically talk about weeb related things
It feels like our "friendship fire" has died out on my end, but not theirs.

I feel like such an asshole for suddenly wanting to break off our friendship (and I also don't think I'm ever going to find this good of a friend ever again considering it's hard for me to make friends, they kind of pushed their way into me without me really noticing) but for a couple of months to a year it's been nothing but negativity. I try to be there for them when they need me, but it's just been emotionally exhausting since this has been happening for a long time, and I can't vent back to them because they always shoot back with
>"you have no reason to complain anon when I have it so much worse"
>"you think thats bad? I have to deal with... etc"

They're not a jerk to me but I just can't seem to deal with SO much negativity from their end constantly being thrown at me, and I'm definitely starting to think our weeb relationship isn't worth staying for

The problem is I'm not sure how to break out of this friendship without them going ballistic, they have anger management issues (towards themselves), and I feel like they'll just try to throw themselves back into my life without me wanting to, and everybpdy will say it was my fault to begin with (I'm bad at talking about my feelings so nobody will understand my grief)

Also very afraid of seeing them at a con since we both frequent the same ones every year and them causing a scene

TLDR;
>I wanna break up a friendship but this certain friend is kinda sorta unstable and I'm not sure how to back out without any lasting damage on their end
