Ok, here is the series of events as it should be, all for the first time of course, since you told me you have seen repeated events.
-Massage to Sam in the kitchen.
-Dinner uncomfortable because she tells you she wants to talk to you about your erections.
-You talk to Sam, and show your feelings.
-Sam gets angry, the next day you can talk to her at breakfast, in the morning and at lunch, the response is always dismissive.
-in the afternoon you try to talk to her again, and the hardware store event begins.
-Then you get home, and have a conversation with Samantha in which you decide to move out.
-After dinner, Molly explains what happened in the afternoon, they agree to go for a trip to the pond.
-After dinner, Emma has invited you to watch a movie, watch the movie with her.
Make sure this is the first time you see this, because if not the switches may already be activated or their effect may not be working due to another one. I hope you find it useful.
