From my understanding after chapter 12.. it seems Ml may not be his mothers child as she stated he needed to learn the sins of the blood he carries (aka the fathers side).
The father may have been unfaithfull and Ml the result of that, hench why the mother "destroys" any and everything he loves to teach him not to love.
It does not seem to me that the mother loves Ml or has any romantic feelings for him. It comes of more like she is punishing him as she enjoying watching him suffer, and the father... well he may be jelous of all the "atention" his wife is giving Ml and feel he is a rival for his wifes love (especialy if Ml isnt blood related to his "mother"), hench the father moving them away from Ml and getting Ml married.
The mother then comes to tjeck if Ml is starting to feel affection to torture him again, hench the interaction with FL.
Also Fl is way to trusting.. Girl the Ml fears his mother for a reason.. yet you have no sense of danger at all... even the servants shows dread at the mothers arival... like read the room.
