Why even bother

My husband and I are fighting again. Seems like that’s all we do now days. His temper is short and he disagrees with everything I say. All I crave is his affection. Yet it seems the more I try the worse it gets. I’m feeling worthless and hopeless. I feel like a failure. I fail at conceiving a child and I fail at being a wife. I am lonely. I am sad. I am heartbroken.
