There is a lot of foreshadowing that he will marry Nora. Also, a lot of foreshadowing that she will cheat on him and they will get a divorce, which is where the next game will start. In my headcanon, I call it "Corporate Kings" and chronicles Alex's rise up the corporate ladder after his messy divorce. If there is one thing you can depend on when it comes to women, you lose them the same way you found them.
It seems like Nora wants to baby-trap the MC, and also get married.
It seems like Lauren may want to baby-trap the MC; while she does not seem to want to get married, she would be totally fine with it.
It seems like Riley does not explicitly want to baby-trap the MC, but would keep it anyway if it meant being in a relationship of some kind with the MC and at least one other girl, like Aubrey or Amber. She is that kind of naive, hedonistic, nice but really dumb girl that means well but causes a lot of harm by doing what she wants.
It seems like Aubrey and MC will have the chance at being married.
Chloe, Amber, Autumn, Lindsey, Penelope, Samantha, Jenny, Naomi and Emmy seem to have no interest in anything more than a GF/BF relationship at most.
Ms. Rose is a wild card. She seems like she could want a relationship, but marriage is unlikely and kids are even less likely. The difference in age, Nora, and the different places they are in their lives also makes anything more serious or long term less likely (but not impossible).
Emily would probably welcome a kid with the MC and would be down with a relationship.
