This is what happens when your Sim is caught cheating (pics)

My sim wasn't married yet and walked in on her live in boyfriend woohooing a townie after a hard day of work. She was very sad, even with the cheerful trait. She hid under the covers a bit and gave herself pep talks, but in the end she saw he just didn't care being noncommital. When she broke up with him she was still quite sad, but he actually got a happy moodlet for being free again.
