female rabbit and male rooster

I was born November 17,1987 (rabbit), and my partner was born May 28,1981 (rooster). We've been together for 7 years, we love each other. I'm aware that our signs are not compatible, we always face misfortunes especially in financial aspects, is there anyway to over come there misfortunes? We're both hardworking and try to save and earn but always end up broke. It's upsetting. By the way our eldest son was born October 20, 2009 (ox), and our youngest was born January 31, 2015 (horse). Please enlighten me. Thank you very much.
