You've had the sneaking suspicion that your fiance Sarah has been cheating on you, but you don't have any evidence. You've known her since you were kids and have been engaged for around a year. Over the past 6 months she's become increasingly distant and 'has to work late' often.

You've come home from work today to find Sarah sitting on the couch talking to her best friend Becca on the phone, not making any notice of your presence.
