Don't dwell. You can't live life looking in the rearview mirror. The truth is that my memory is short. People are either in my life or their not. When they're not, I need not dwell on that decision or even remember why. If I made it, it was probably for a good reason. For those who remain, I need not worry about what you did or didn't do a month ago. Let's worry about today and the days to come.
