I just feel lost..

Y’all... I am so depressed. My son is 10 months old and literally out of nowhere lately it just hits me. My sons father is so on and off with us and is now telling me that we’re done. He says that I “walk all over him” by telling him that he should be with us more than his friends. But I feel like I am just trying to get him to see what should be more important in his life. He currently lives with his parents because when I was 2 weeks pp after having a c section I moved into my grandparents house because he wasn’t giving me the help I needed and I was battling postpartum depression so bad to the point I was in denial and all my friends just kept telling me I wasn’t myself. Idk what to do anymore.. I feel like I’m constantly fighting for my family to be together but my sons father just keeps playing me over and over again. One minute he says he loves me and the next he is saying we’re done. How do I move on.. I don’t want to. But I just don’t even know what to do. I prayed my son wouldn’t grow up in a broken home and I really want to work things out with my sons father and be a family but I have finally realized that I can’t make a man grow up and want to be a family with me... do I ghost him completely and see if he even cares? Do I try to fight for this family even though I’m the only one fighting? I just don’t know and with it being the holiday season it makes this so much hard. If you’ve read this far seriously thank you.. I just needed to vent. None of my friends have kids so none of them get how hard this is for me.
