Granted, it has been a while since I've played, a few months I'd say. IIRC she said all that in a fit of rage and shit started going down with the swapped father, he gets kicked out of the house and AFTER all that the mother actually falls in love with MC, instead of just having him as a side snack.
Oh, right, thanks bro, at least the bastard is out.
More complicated than that, as I remember:
1) Mom goes for son. (As part of how broken the game is, it assumes you reciprocate even if you refuse sexual advances.)
2) Mom says "let’s meet every afternoon like this"
3) The first time you are not there for the afternoon slot, she goes back to the abusive not!dad and you walk in on them the next time you come home.
4) MC looks at them angrily, not!dad tells him to get lost. He gets lost, mother follows and insults him for not being "man enough" for her.
5) She goes back to the abusive not!dad.
Later he starts hitting her and she hides in her bedroom for a while, also he goes berserk on MC’s and sisters stuff in the basement.
6) The sister runs away from home.
7) The mom decides that not!dad has finally gone too far and throws him out of the house.
8) After some days, the original dad returns, apologizes for everything "he" has done and everyone forgives him. He and the mom are back together, presumably.
So… the only time MC is not a side-snack is when he is a rebound after she threw out the fake father… before going back to being sidesnack once the real dad returns. There is also something about the fake father leaving on a business trip for a few days in the middle, I think. The order depends on how far you are with two different storylines (mother and sister).
Intentional humiliation of someone who wants an exclusive relationship with a woman by fucking the woman in front of him, then insulting him and then having the woman insult him too… sound very much like NTR to me, even if you might consider the MC an idiot for thinking that the mother would leave her old relationship for him.
