I wasn't gonna comment but for sake of diversity I feel you deserve at least one good one. I'm actually quite close with one of my exes from 13 years ago. We dated when I was graduating highschool he broke up with me (very respectfully. He basically just told me I deserved someone who liked me as much as I like them, and he was right).
Anyway, he and I didn't really hang out much or talk much for a while but we were in the same community and would see each other at metal shows all the time and weren't unfriendly but would just kind of live our own lives. Once my ego healed a bit from being dumped we did hook up a couple times. Then some time passed and I met my partner of now over a decade. Anyway, me and the ex still chat, he's met my partner and they get along very well. My ex is a genuinely kind and funny guy and I would be a reference for him any day and I consider him more my friend than my ex at this point.
I really do think time apart is important because they need to become not a constant fixture in your life before you can repair the relationship to "friend" level.
Oh my friends and I argue for fun all the time! I actually find it a really forgiving space since we all struggle with things like RSD and I think it helps us learn to communicate when we are feeling things like that.
It's really refreshing and nice not to have to mask my autism as well.
Its also very interesting because we all have our different special interests to infodump about :)
It's just a really colourful and loving group and it truly feels like a family (tbf we aren't all autistic but many of us are and even more of us are ND--def over 50%)
I love this grotesque style, keep it up!
