Yes, I tend to think that “Rey shouldn’t love abusive man” is a sort of one dimensional way of viewing their relationship.
What other way is it? She fell for him because he has a nice body (TLJ scene) and because JJ Abrahams wanyed to redeem another villain so badly. Kylo is a man child, he is a murderer and the only interaction he has with Rey is during fights… Its so messed up.
I think it’s quite obvious that they came together based on their lives and growing up lonely wanting a family.
