Be Cordial and Friendly

I know how hard it is to be friendly, especially after finding out my BF cheated on me (again) and is a compulsive liar. I erupted like a volcano on him and dumped him FAST. But I soon realized he had some of my things I really wanted back. So after a couple days, I contacted him and asked (NICELY) for my things back, and we were both very kind (but to the point). Who know what will happen down the road, only time will tell.
