Bella discussed a bit more about her husband (this is seriously dragging on though, the mc should be like, "If we're gonna be dating, you need to tell me what the fuck the situation is...)
The MC can't demand much since he and Bella aren't actually 'dating'. They just enjoy each other's company and have casual sex, it's all very shallow, at least on Bella's part, while the MC, on the other hand, knows he wants to be with her.Every main LI relationship except Bella's is now out in the open.
I think Bella's route was made to be the slowest route in the game. Their relationship will only progress when she gets a reality check and realizes that she could somehow lose the MC.
