Because they saw their ex with someone else and couldn't deal. Because their crush didn't notice them. Because they were in another breakup. Because they were still together but he forgot their 2-months-together anniversary. Because they had a contraception malfunction or caught herpes. Because he hadn't texted in 2 whole days! The reasons are limitless. How much of that pertains to the game, though, who knows.
Hope your gloomy tearful roommate isn't making you hate the game. If that were my game, I'd get my Sim turned into a vampire, and Drink Uncontrollably til my roommate problem was all gone. >:)
