Now and then, people do change for the better. That usually takes them being able to take a long, hard look at themselves. It involves self-criticism. Is your ex that kind of guy. Actually, it really doesn't matter. Whether he stays the same as he was, or transforms himself into God's gift to women, is kind of irrelevant to you and your life at this time. You are definitely investing way too much thought in a direction that serves no purpose.

The bottom line is you are no longer important to him. He has moved on. You think about him every day, almost every hour. He might think of you once a month. Let go of what you don't have, can't have and won't have. You are wasting your precious time. Life is full of good things and good people that you can connect with. But, if you sit around daydreaming about the past, you will lose out on what the future might be. In a way, you will kind of deserve to lose out.

You are being rejecting of what life could offer you now because you didn't get to keep what you once had. It's your choice, but that's not an approach to life that ever did anyone any good.
