I apologize that this isn't really a "heavy" topic but kinda is? I don't know, I honestly don't know who to turn to with this matter because few of my friends have been reduced to non-OC group.
My issue:
SPOILER (click to toggle)
Me and a certain friend created an AU fanpet for a couple of years ago. Though, due to our differing opinions and drifting out of a relationship (platonic), we have, sadly, burnt the bridge down. We never talk ever yet the fact that we created joint OCs together makes it difficult to get rid of them despite not wanting them anymore.
I don't want to look like an asshole who ditched project because of a falling out at the same time don't want to keep characters that do not really tune to my line of world building (I purely focus on my world than integrating Fanpet AU OCs.)
I'm really torn of respecting our created characters (but we don't even talk nor even say Hi anymore, what's really the point BUT I don't want to be rude???) and going things my way.
I hope I can at least get an opinion from an outsider or someone who felt the same way? What would you do in this situation? :(

;; get rid of it. don't waste precious pet space on a pet you will never use. especially if it brings up bad memories. should ya'll become friends again, you can always create a new pet. but until then, it's not worth it.
I've had to do that before - I got rid of all the ties I had to it. I felt so much better afterwards too.

Yes, I actually had to ditch it, swapped names (I had to buy CSC just to do it, the pet is nearing Gourmand so there was no choice.) and pounded. It was a nice feeling. I just feel bad things didn't work out.

Feeling bad about that is normal, it'll get easier. I used to write an AU with a then friend and then they just... went weird and I lost that entire AU. It hurt for a while but after a few weeks, it stopped stinging so badly.

It sounds like you've already made some positive steps forward.
I sort of went through the same thing last year (adult life and mental health issues had us drifting apart, but we're still on 'friendly texting' terms) and it still hurts. Haven't really been able to write since it ended, so that's something I'm still personally working on. The loss of any relationship is hard to deal with, especially when it was a world-building/ world-consuming one, but I'm glad that you're healing and heading in a better direction than before! Good luck!
