Omg!!

Hi all. I'm pregnant with my second child. I've never felt so alone. My first child's dad has nothing to do with us. And this ones dad says he's going to buck up his ideas and sort himself out. I brought everything for baby so far and all I get is I'll give you half but don't actually receive nothing. I'm not scared of being a single parent as I've managed before. But I just don't want to be going down the same road I did with my first. All I keep getting is false hope, empty promises, and "if you need anything let me know" when I need him I can never get hold of him. He's always on his phone apart from when I ring him. Sorry this is so long but I have no one to talk to. I'm fed up trying to talk to him and nothing gets resolved. I'm scared I'd hurt his feelings cause he suffers with anxiety, I've tried my best to help him for over 3 years and its getting me down. Any help would be appreciated. Thank you.
