What Comes Around--Goes Around, So They Say

What comes around- goes around, or so they say. I would love to know if that's true, but it does seem so. Ever since my ex has cheated on me and we went our separate ways, he has run into some problems. First of all, he was on top of a roof, on a ladder and fell off!!! He was out of work ( he is self employed) and was unable to work for about 6 months. The next thing that I knew, once he was healed and back to work again, someone hit his work van and totaled it out leaving him to have to buy another one when he was nearly finished with the payments of the old one. Does he associate all this bad stuff with what he got because he treated his family so horribly??? Probably not. How long will this karma stuff keep getting to him? Interesting.
