Well, we haven't seen Minerva's husband yet. Maybe Stan
is an upgrade.
Based on what we picked, I don't think appearance is necessarily one of the aspects that Minerva is discontent with her marriage. It looks like she is the primary breadwinner in her household due to a twist of fate, but her husband is not picking up the slack, so she is the one that have to get shit done or none else will. When we get to that situation, yeah, looking like a potato sack doesn't help, but that is rarely the main issue
That is one of the aspects where Stan could have easily appeared more manly and he utterly failed; and I hate to agree with Louise, but when rent goes up and he passively took it instead of pushing it to keep it down for as long as he could and immediately talking about it with the other two tenants (Louise and Lena), can only be described as a bitch ass move. If those Stan changes counter don't improve his attitude, so he can be more proactive and speak for himself when needed, and maybe give a piece of his mind when Louise tries to belittle him, I don't see him as true LI material except where a bad Lena can cuck and milk him out of his savings
