will he ever pay?

I am one month NC (taking a bow!) and I am currently struggling with the thought that this jerk used my goodness and love, lied, cheated, manipulated and discarded...but now he has moved on happily without regret, pain, or any of the horrible feelings normal people with emotions experience...he is having fun with another woman, feeling wonderful about himself and justified for dissing and ditching me..meanwhile I am feeling sad and rejected, struggling to let it go and move on...it doesn't seem fair at all...is there any karma for these dipwads? Is there any comfort in knowing that he will get his? I know he doesn't miss me or feel bad about how he treated me...but I really need to feel like he'll get his...I know that I'm supposed to find this within myself, but that alone just isn't getting it for me
