Yes, that's right, I was wrong - the correct one would be Lenny. Andrew can dump Anna HIMSELF after learning about her intimate affairs on the side. In this case, fat Lenny, who has money, will be the option that will allow Anna not only not to be alone, but also to have fun on the side.
This is an option.
Personally, if I wanted to fuck around as much as Anna, being on my own would be a priority. If that's the kind of lifestyle you want to pursue, why would you potentially limit yourself, by having a largely irrelevant partner cramping your style? Maybe a lot of us would choose Anna to be with Andrew or Lenny, because we'd enjoy her cheating on them. But from her perspective it makes little sense, once she decides that having fun by fucking around, is more important to her than trying to be faithful.
In those circumstances, the only way such a relationship makes any sense for Anna long term, is if it's a specifically netorase relationship, with her as a hotwife. Because long term she isn't going to be able to keep Andrew or any other chump in the dark, about her infidelity forever. Sooner or later they'll discover the truth, and unless they're willing to become a cuck, then the relationship is likely to end eventually. Recent content suggests the Devs have recognised this, and are in the process of setting up such a scenario for her and Andrew.
I recently asked Deep about the choices we made regarding Anna's future relationship with Andrew, and he confirmed that whatever decision you made back then, will eventually happen. So if you chose for her to leave Andrew, eventually she will leave him. If you chose for her to become faithful to Andrew once more, then eventually that will happen, and you won't be able to stop it. And if you made the middle choice, then she'll stay with him, but continue having fun with other people, which heavily suggests that Andrew will eventually become somewhat ok with that (and he'll become a cuck).
So it seems, that for at least the forseeable future, we'll be able to continue to choose who Anna has sex with for the most part. But at some point those choices we made, will come into play, and probably start to limit what we can do? So if you chose to leave Andrew, content involving him will likely get blanked out? If you chose to be faithful, certain content with other characters will perhaps start getting blanked out? But if you made the middle choice then probably most content would remain available, except anything specifically aimed at a faithful relationship with Andrew or a similar relationship with another character?
