I am really curious dose he really love Courtney or not cuz in one chapter he said that sh...

To me it felt like he fell in love during him courting her. And since she fit his personality it was insanity and love for him he liked how she treated him with disgust and I m guessing he liked that she wasn't like the other women who would've ran away when forced to do his naughty plays. ╮(￣▽￣)╭ he just fell for her in the process of marrying for convenience

In the novel is possible to see how much he loves her and he thinks she’s pretty. It’s always described how he looks at her with love and care in his eyes

Awwwww

Yeh that's kinda makes sense

I do think he finds her attractive. At least that's the impression I got. In chapter 43 he said her personality drew him in, but he wouldn't have married her if she wasn't his type. I think through his actions he seems to care a lot about her.

Yes, I interpreted like he wouldn’t marry just anyone because they’re into bdsm. He does find her very attractive (but other people think she isn’t a striking beauty and her looks are rather common, which doesn’t necessarily mean she’s ugly)

A paragraph from the novel:

“ They had been married for just over a season, and in that time, Richard had come to know Courtney deeply. She was no longer just the idealized figure of his imagination. She was his wife, his partner, and his source of strength.

Though Courtney’s exterior was composed and unyielding, her heart was tender beneath the surface. This didn’t disappoint him—in fact, he admired her strength all the more. She was resilient and determined, able to stand firm and rise again even when momentarily shaken.”
