This is little bit older story, so the plot is as it was at the 2015s: the ML is a spoilt child who never learned how to play nicely and be true to his feelings, and FL ready to be stupid and obedient for/to the man she agreed to be hers.
So him being manipulative, selfish abuser is vindicated by his 'love' for her. He basically destroys her business and any chance for her independent income and home in order to make her work for him and live with him.
When he finally succeedes, his mother comes along unhappy with FL's background. Mother and son together pressure FL to sign a pre-nup promising, among other things, to leave future children with them in the case of divorce.
Here FL's gets an Epiphany (because being MOTHER is above all) and finally refuses, to what ML gets a fit or rage accusing her of selfishness.
I won't spoil any more. Something that could heve been an interesting story (two people from different walks of life, with woman being educated and independent) became yet another poisonous Cinderella story.
