Need HELP with affidavit of support I-134 and I-864 for a K-1 Visa.?

Hello I have a question concerning the affidavit of support I-134 and I-864 for a K-1 Visa. I am from the USA and my fianc�e is from the Philippines. I am recently divorced I have not had any income for the last 3 years so I have no income tax returns. However I will be receiving $20K per year for the next four years in alimony. I also own my own home and auto. I have $40k in the bank. Do you foresee any problems I could have with the affidavit of support? If so why?
