I have nothing

I have nothing, he took that all away from me. I left when I found out I was pregnant and he's made my life hell ever since. I can't have Facebook Bcuz somehow he finds out what I post. I can't have Instagram Bcuz again he finds out what I post. I can't do anything without him finding out. He's everywhere and has others telling him what I do or post. Going private doesn't even do the trick and what's the point of social media when we can't even have friends Bcuz you don't know who's telling him information. It's just not fair. He threatened to take my baby from me, fight to get full custody. I know he won't win Bcuz I'll be a damn good mother but how am I supposed to enjoy pregnancy when I know what's at the end? Court. And if we get joint custody? I'm so afraid he'll take him away from me. How can anyone live this way? The knowledge I'll have him in my life forever? Sharing my child. I'll never have any peace, he'll ruin everything.
