I believe the point of many things in that game are supposed to scare people. If they weren't terrifying, the designers have failed.
Two of my friends just started dating and can't keep their hands off each other. Fine, but I'm getting over a breakup and watching them makes me sick. I've told them exactly why it bothers me and have asked them to tone it down in front of me, but they have refused and told me to just get over it, and I can't avoid them in favor of other people since this is a small town. Keep in mind that I only managed to recover from said breakup in the first place by hanging out with these people. How do I make them stop or get over it?
I have been trying to get involved in another relationship as quickly as possible just to stop the anger and jealousy, but that's probably a bad idea too.
