Need advice with child's father

Hello everyone I am a mother and believer, I did not grow up religious and am still struggling in my own ways with sin but I pray, study the word, and am doing my best to overcome my sin. My child's father and I have never been married, he says he is a believer but certainly is not saved and uses a lot of demonic symbolism in his art work. His life has been terribly traumatic , he is battling addiction , and I strongly feel he is possessed. I know he has free will, and I am protecting my kids and I. We are no contact , but my heart , I still love gim and despite logic want to hope that he can be saved and we can be a family. I'm confused because I know things are different since we are not married, but he is still my child's father and I just need advice on how to know if there is any hope for reconciliation, if it will ever be in Gods will if he turns to God for him to be my husband or if I'm just delusional. I've been praying using prayers that are for unsaved husbands even though he is not my partner technically, I feel lost and doubting myself a lot. I know for certain we can not be together any time soon, but how can I move forward without deciding whether it's forever or not ?
