I mean it's motivated reasoning and deliberate equivocation. Mahoro is in the process of building a case for divorce, so she has to make Rei into a bad guy (in her head) to justify (to herself) some of her actions in that pursuit.
Happens in practically every divorce proceeding. People know they're doing something wrong, and they don't like feeling guilty about it, so they come up with excuses and maximise every perceived fault in the other person and minimise every fault of their own.
True friends are supposed to be level-headed and push back on this stuff, and pull people out of destructive blame spirals instead of enabling it and enjoying the drama. Sadly those are pretty rare.

I completely understand what you're saying but am appealing against that nature just as those true friends your referring to would do.
Equivocation often amplifies the emotion felt and that justification can also quite easily lead to rash decision making, resulting in situations like Mahoro also cheating and thus being seen as just as bad.

Ensuring we take a step back and defining things for what they actually are helps one keep a level head and avoids us succumbing to poor morality and adopting an antagonistic role ourselves.

That's it.
He is Shojo/josei equivalent of the super famous idol who is also a manga otaku and falls in love with our gloomy protagonist for no reason what so ever and/or the ultrahot Queen and/or warrior from the isekai world who ruins her panties at the presence of the MMC.

he just seems young and casual even tho he helped he doesn't really have much 'stake' in this so i guess he can be objective about advice and stuff tho idk if it'd necessarily work out romantically
