Remove the hard mode core? Talk to Lisapi and switch to normal mode, hard is not for you. Hard is designed to be grindy and suffer in exchange for small extra rewards. It's not going to change and I'm not going to do anything optional (apart from pregnancy, the only thing optional). In future versions the mood will be more balanced, now it's just implemented. What about the not-progress thing? Make the girl not angry and continue your adventure, it's not complicated, just very grindy.
As an extra note... I have to check but I would swear that even if she's pregnant + turned off seeing her pregnant you can spend time with her = not getting angry.
Anyway, again, I recommend you to change the difficulty instead of suggesting me to make the hard mode an easy+ mode as it was in previous versions...
