Postpartum depression

My baby daddy hasn’t been a lot of help. He won’t get up with her she’s 3 weeks old. And when he tries to hold her she just cry’s. And so I pick her up and she’s fine. But it’s been hard because I guess I have this imagine of a guy who would help me and love her as much as I do. But he doesn’t. He comes home from work and sleeps or drinks. And when I ask for help he always tells me I’m capable of doing it. I hit such hard bottom that i started hanging out with my old fling guy. And he has shown me what it feels like when a man can actually be there and help me with her. I don’t feel guilty for going to his house all the time. Because I think I’m just done with baby daddy. And i known I hit depressions because I don’t care anymore. I could careless about baby daddy and his doings. What do I do. Please don’t judge.
