Should I keep praying?

I recently ended a friendship that I felt that God didn't want me to have. There were many warning signs but I still held on until I was forced to let go when he did something that hurt me. I knew I had to let go for a while but part of me was afraid and didn't know how to. Now that I've finally ended the friendship, I feel free and unbothered but at the same time part of me is sad, hurt and disappointed. I also miss him and part of me wants him back. I've been praying and feeling better day by day and I've also been praying for him not only because I genuinely loved and cared for him, but also because the Bible says so.

My question is, even if God didn't want us to be friends, should I keep praying for him as someone that hurt me? Or should I stop? I pray for his healing, his job (he just started a new one), his life, family and friends etc. Thank you for any advice.
