My husband constantly snaps at me

He’s constantly snapping at everything I do. I look after our baby, do the housework, cooking, washing, everything and I just feel like it’s never enough. He doesn’t even get up in the nights when she cries and I’m just so drained. I can’t even be bothered to attempt to fight my corner or stand up for myself because it always ends up being my fault. He snaps at me and has tantrums constantly, moans he’s tired and yes he does have a stressful job but it’s no excuse to take it out on me.

Sometimes I just wonder if it’s worth any of it and if I’d be happier on my own.
