I broke up with my ex for more than a year. Then 1 day we accidentally met on the street then we went for dinner together. Since then we meet once or twice a month (without anything intimate, not even holding hands). Usually we just meet for lunch, dinner. Yesterday I cooked something and invited him. He brought wine and flowers to my place. He was hiding the flowers from his back and surprised me. Does friends do such a thing to show you’re thankful for the invitation?
