How do you deal with a broken heart?

A little while ago I had to run to the store for some things. On my way there I saw a boy that I had worked with for over six months. He was saved and had been doing well in his spiritual growth. Then his father called and told me that I would no longer see him at the church or be allowed to contact him again. This, of course, was a hard thing for me, but I had no choice. That was over a year ago. I have seen him from time to time and have prayed for him daily. Today when I saw him I waved at him as I drove by. I then looked in the mirror and saw him take off his jacket and jump up and down like he was mad. Then, just as he was getting out of sight, he filpped me off. My heart was breaking at seeing his reaction. What had I done to him, or his family, to cause such a reaction? And now I struggling with the saddness that this has brought to me. I will continue to pray for him and his family and let God deal with him. Mav
