I just wanted to get out of the marriage. She had quit a bit of money in her account from her inheritance when her mother passed. I was under a lot of mental stress. Now I have to pay her $150 a week for 4 years. She makes more money an hour then I do. I work more hours so I make more. But she has no debit I have almost $20k.
Your divorce decree is the best place to start. Does it say Modifiable alimony? Lifetime alimony? Alimony for x years or for x amount? Your next best place would be to file a Motion to Modify alimony. The court's threshold for modification is however "substantial change in circumstances" (for your income or hers).
