I think the seperation will happen in 2 stages between Ana and David...First there will be a huge fight between them where they'll live in seperate appartment/room....and there will be an issue of kid ...who will have the child... That's the time where in corrupt path we will see Ana going whore and David working while Ana's mom taking care of kid when David or Ana work for office and David might go off to take care of his business...that week maybe next week storyline will have more scenes. Where David will get some proof and meet Alexia and everything...In faithful and uncertain path Ana will keep pushing everyone away but idk I feel like in uncertain path she'll get atleast one sex scene with some antagonist with slow corruption scene that ultimately grows into sex.
When David will return from his work tour with proof, and depending on how we played Ana's character....that's the time it will be decided whether they'll get back together or want to move in together. This David work tour will be the turning point of the story. The number of days he will be out of city will be the number of antagonist getting Ana.
As of now , for this week, we will just see fight grows upto the limit of living seperated and jealousy grow to max points and on the verge of divorce... Decision of divorce will be taken after that. That's the time where David will have his say to Ana. And face kendra.
