Bronwyn Ingram, who Filner introduced as "the first lady of San Diego" served as a disability analyst for the Social Security Administration, but when Filner took office, she led an effort against homelessness in San Diego.

Ingram and Filner began dating in 2009 and were engaged since January 2012. Their marriage would have been Filner's third and Ingram's second. Filner is 70 years old Ingram is believed to be 48 years old.

Media partner 10News obtained the following letter Ingram sent to her friends:

Dear friends,

With great sadness, I must inform you that I am unable to continue my efforts on behalf of the homeless population in San Diego. I am dissolving my volunteer organization, Team First Lady San Diego. I want to recognize the hard work and dedication of all of the TFLSD volunteers and I hope that you will continue performing the wonderful work that you do within your communities.

I have broken off my engagement to Bob Filner and ended our relationship. I have struggled with this decision as I really wanted to see the community projects we had initiated with such enthusiasm come to fruition. I am extremely disappointed and heartbroken, both for what Team First Lady could have accomplished, and for me, personally; however, this is the only action I can take given the devolvement of our personal relationship. I wish Bob the best and sincerely hope those who have worked so hard on behalf of Team First Lady will continue their efforts in the same spirit of generosity for the communities of San Diego.
