The sister and her husband are disgusting. The sister cheated first so I don't give a single fk that the husband also cheated. But he impregnated his mistress, didn't do anything for her and she ended up killing herself. The father shouldn't have covered for them either.
Wow everything was stupid, the FL sister and FL brother in law are so dumb that they ruined their entire family for 8 years. If I were FL I would not have forgiven them and both ML and FL are also dumb and stupid!
