Struggling with breakup

My ex broke up with me 6 months ago and while I am over him it’s hard for me to be indifferent towards him. He played the classic love bombing game which later turned into treating me very poorly. I would necessarily call him mentally abusive but i definitely and traumatized by the way he treated me for the last 6 months of our relationship. I am genuinely over him and am very excited for a new and healthy relationship however, I find myself struggling to want any kind of goodness to come of his life. While I am not currently seeing anyone I can already see the ways in which he treated me affect my future relationships. The Lord commands us to love everyone but I don’t want him to have any kind of happy life after what he has done to me. It’s seems so unfair to me and everything I did for him just for him to lead a happy and fulfilling life. Any advice would be helpful
