You know one thing that came in up in my thoughts was that Stolas didn't have to make his life so...miserable. From what we saw from before the affair, Stella mostly just ignored Stolas. Sure, she insulted him sometimes but she never forced him to do anything he didn't want to do. When she threw the "not divorced" party, she literally said he could come if he wanted to. She didn't drag him around and say "look, this is my shitty husband". Stolas could very much try to get along with the other goetias like Stella does but he just doesn't.
Now if the show you know SHOWED Stolas trying to talk with other goetias but they just brush him off because he doesn't fit the mold, this would give Stolas some actual sympathy here and could also be an explanation for why Stolas is so obsessed with Blitzø and his attention. But we don't see that, and in fact, Vassagio is proof that Stolas could be friends with other goetia that would like him. But no, just be moody at the social event and grumble at your wife socializing with other people. Pretty much just this 4chan meme right here.
