Long lost sibling

You're the woman in the picture. The guy in front of you is Mark. You and Mark have been married for seven years. One day, while going out for a walk, you see Mark with another woman who is visibly pregnant. Angry that he's cheating on you, you immediately return home and find a note stating that he'll be gone for a week on a business trip. Reinforcing the belief that Mark is cheating on you, you go to a divorce lawyer and get the divorce papers. A weekend later, Mark returns home with a bouquet of your favorite flowers. In a fit of rage, you hand over the divorce papers.
