How can I convinced my wife that I wanna climb up to be successful like I was b4 after 1yr plus of my downfall?

I started off from scratch since we got married 8 yrs back. But for the past more than a yr i was down and she been helping me on some of the household rezponsibilities. Recently, she started to become impatience abt it while im in d process to reach to what i was last time. She started to say words like divorce everytime we had an arguement. I know i fail to fulfill my task for the past couple of years but i always believed that im now at d right track to pull her out from all this problems. But you know in business we have to build up slowly and learn from the past mistakes. I love her so much but i dont know how can I convinced my wife that everything will be as what we are last time in a couple of months from now. Can give me some advise please.?
