I don’t remember anything ever happening or them spending enough time together for either of them to fall in love. And that’s my only qualm

Right at this point they're not in love, they're simply attracted to each other. Physical attraction and curiousness you could say, and it's that way for some time actually (some months). Now that the duke is back, their time will increase and they will properly be with each other. This isn't really a spoiler but they spend every night together for at least a month and they actually speak a lot (most of their interactions are that way actually, at least during the first half of the novel).

She can't... she can but can't... spoilers ahead
She made herself unable to have children on purpose, precisely so it wouldn't pose a hindrance to her future. She can make herself have children again as she knows what medicine she needs for it, but she willingly decides not to take it for the longest time. Specially since the duke doesn't want children either due to his special circumstances...

I wish that at least the art was pretty. Like it’s not bad art but when the story and characters are lacking art makes up for it sometimes but even the art is meh compared to other yaoi

It’s not about whether I can draw better art. When comparing the story and art to other yaoi manga, this one is lacking. The story is not very good and the art, though not terrible or ugly, doesn’t add anything.
If you go to a restaurant that’s just ok and then go to another restaurant that’s 5 stars then comparatively the review and rating will be lower. Does that mean that you can cook the food like the just ok restaurant? No, but you sure as hell can taste the food.

yeah...you are correct.. but the thing i am telling you is when someone do something that we cant or if that person do a better job , we must respect them for that... if we be mean to them they will get hurt..... imagine if you draw a manga and you did your best and post it on a site like this and someone leaves a bad comment ...how will you feel? i think you will understand what I am saying... and i like your logic.....
I don’t like the ML but I also don’t like the FL so there’s that
They're competing for your dislike
They really are. I don’t like the way the ML talks but I can’t stand the FLs personality
I understand ╮( ̄▽ ̄)╭
