Damn, I don't even remember that coming up. Oh wait, was that when Sandra asked about your future together, and if you wanted a family? Yeah I picked the no family option there. Well that would kind of suck if that is what causes it, because why give you the option at all if there's only one correct choice?
I agree but that's it I had the same thing I imagine he intended at the time for it to be more a a realistic option but ended up fucusing on the other path too much. I replayed again from the beginning and selected yes it's still a fun story so it wasn't too annoying and you can skip a lot if you remember everything
