How important is the Affidavit of Support form for the K-1 Visa?

The Affidavit of Support is necessary as a guarantee that the immigrant will not become a public charge. Immigration is a privilege, not a right. If you don't make enough money, then you can get co-sponsors. Surely you have family or friends willing and able to co-sponsor a financially secure man who loves you. 125% above poverty level is not a high standard.
