Help I married a Wood Tiger!

I'm fire snake 31.01.78 and he's a wood tiger 09.01.75. Our marriage is really strained and I'm finding his aggressive outbursts unbearable. He's been very unlucky in his career and health. Our financial situation is very tough and we have three children. He is good father but our communication is strained.

I'm feeling disrespected often. Please advise me on what we can do to save this marriage. Thank you in advance.
