If you have had a sim move in with you or have the "romantic" option for them, you must be pretty close. If you are playing one sim and your special someone is doing something "romantic" with another sim behind your back, you will atomatically walk over to your boyfriend or girlfriend and begin to yell at him/her!(Unless you press the triangle button before you get to them.)It will be a big fight which will bring your relashionship down to -4 or lower! Keep an eye on them at all times!
