I agree with the notion that the husband seems very much like an average, mediocre guy who is similarly to Yukako caught up in an endless cycle of never-changing routines. This chapter made him out to be less of a dick than in the first chapter, so I have a hard time seeing him as some sort of big shot bad guy.
That is of course not to say he's likeable in any way, nor are the other characters particularly so either. It seems part of the point of this series so far that no one here are particularly bad nor good, they're all just flawed humans that have ended up taking the 'easy' route through life.
I also didn't really understand the scenes with Chinami's clothing, but I'm guessing it's highlighting how she's torn about a youth love and the current shitty substitute situation or something similar.
