Heart broken

Asked my husband to prove me wrong tonight. I found something on one of his phones and he wouldn't. He wouldn't even talk about it. I have nowhere to go. I've a two year old asleep in bed. I'm nearly 30 weeks pregnant on our second and all he seemed to care about was if I'd finish the Xmas shopping tomorrow woth his mother. How the hell am I going to do this. I have to live here. Nobody has room for me and 2 kids. 12 years together. He's all I've ever known.
