These kind of anime shows are targeted at the folks who tend to be big anime fans. It's escapism, showing a world where even they can land the best girl in the school. It's not meant to be realistic.
Weird choice of anime for this, in this one the MC is actually super dependable, charismatic, helps anyone when asked, is popular and even used to be vice president of the student Council.
Not trying to deny your reality, just saying that it's rather a problem with too little cooperation and compromise than a problem with divergent dynamics. This is speaking from personal experience.
I'm more of a homebody (who does their own housework, so there's that) and I actually seek out partners who are more outgoing and social precisely because I can compromise with that and said compromise leads to a relatively organic way of incorporating more social contexts in my life (organic as in not requiring me to go out of my way to get them). And, from what I've seen, the other side of the compromise - partaking in more shared activities while cloistered (in which I include housework, cooking, financial management alongside other recreational activities and such) - seems to be well received. But, of course, this implies possessing the willingness to cooperate and compromise (within reason), which are two of the most important requirements of a functional and healthy relationship.
In short, my experience is that the grand majority (say 90%) of my previous relationships have failed at a collaborative level, with the outliers being due to other major and unrelated factors (past traumas, familial troubles, poor timing, etc.).
It also helps that like 80+% of the time the guy is the one otaku who is relatively physically fit, reasonably grooms himself, and has at least a modicum of social skills (even though they temporarily have no friends before making 3 dozen)
Every once in a while though you get something like the first few volumes of watamote where the main character is genuinely a fairly reprehensible person who constantly makes things worse every time they try. Though to be fair even that ended up with tomoko somehow gaining a pseudo harem
