But...in your own quote from Riley he says that while it bothers him sometimes, him being physically weaker than Buffy isn't the determining factor in why he's upset.
But it is
a factor and that is not good. He is threatened by Buffy's strength and she doesn't need to be putting up with that crap. She deserves someone who will allow her to be as strong and as independant as she wants and not be threatened by that.
I think @Yosso nailed it. Riley isn't a dick. He doesn't think that women should be subjugated to women. He's old fashioned and sometimes that makes him to make comments like you outlined. That doesn't mean he treated Buffy "appallingly".
"Old-fashioned", ie stuck in a time where women
were subservient and misogyny was more prevalent than it is today.
I don't like the "he's old-fashioned" explanation, because it provides a screen to hide behind and makes excuses for sexist and/or misogynistic behaviour. And Riley
did treat Buffy appallingly towards the end. He cheated on her, blamed all their problems on her and issued her with an ultimatum, putting the guilt entirely on her shoulders at one of the most emotionally turbulent times in her life. He's an ass.
And while I'm not calling you out or anything, I'm curious as to why you didn't choose to address the other parts of my posts. Namely, the part about the crap Riley was going through as well. I mean, why doesn't Buffy get called out for understanding what he's been through. I hear all the time about how Riley picked a colossally wrong time to be needy, and I agree with that, but why doesn't it work both ways? Why doesn't Buffy get called out for not really showing any empathy for Riley? Because she's the girl? I don't understand. Really, I don't.
Alright, I'll adress what Riley was going through.
In Season 4 I do feel genuinely bad for Riley in episodes such as
Goodbye Iowa and
The I In Team. His world is crumbling and everything he believed in is proven to be a lie and the drug withdrawel just looks painful. I think that he was forced to come to terms with who he thought he was
supposed to be and that was hard on him. And I think that Buffy is supportive and sympathetic to him during that time and does what she can to get him through it.
However, in Season 5 he seems to have gotten past it. He's adjusted somewhat to civilian life and he seems to be doing alright. All his issues in Season 5 seem to come from the fact that he's not "Action Guy" anymore, therefore his girlfriend is doing all the heavy lifting, something he is not comfortable with due to his views on gender and masculinity.
I read an article (I wish I could link it but I forget where it is, I'll try to find it) where the author discussed how focused on being "Action Guy" Riley is. He refuses to make peace with the fact that he just can't be that guy anymore and because of this Buffy's strength threatens him. He could have become research guy, reconaissence guy, weapons guy etc. He could have found a comfortable and helpful niche to fit into but he refused to, thus creating his own issues.
So there's no confusion, I don't hate Riley. He has some great moments (I particularly like the scene where he rescues Oz from the Initiative). However I do find a lot of his actions in Season 5 to be very problematic and I don't like the way he treats Buffy.
Re the meaning of misogyny. At the simplest, most basic level, yes misogyny means the hatred of women. However, misogyny covers a
much broader spectrum of prejudices, negative attitudes and feelings towards women, from slut-shaming to violence against women. It is not just an extremist issue.
And fine, you don't like Wikipedia. I will link in some articles/essays from some different sources once I have time to look them up.

Those should be a good starting point. They all talk about extreme misogyny as well as more subtle misogyny.
