Have you regretted your ex relationships?

We are still in contact with my ex-husband because we have a baby. I don't regret having a child, but I regret having him as her father. He is constantly trying to interfere in my life. He is a football player and his career which was going very well when we were married is now going very badly so he literally blames me for the team he transferred to, etc like I ruined his life and then just left? And he keeps saying that I am a bad example as his child's mother. I am so overwhelmed that I don't know what to do in such a situation? I wish I had never met him I even want to go to the police, but what can the police do? We have joint custody.
