Mary has filed a lawsuit in Davidson County, Tennessee on May 8 against John, her husband of 42 years, reported Aceshowbiz.
In her petition for annulment, Mary stated, "No person in Tennessee can marry another while being married at the same time of the second marriage."
Although she and her husband separated in 1996 because of John's alcoholism, infidelity, overspending and hoarding, the 63-year-old insisted, "I love my husband and I don't want a divorce."
Mary also noted that she found out that John married Tricianne in January from a wedding announcement in the local newspaper in April.
The retired nurse and university professor further added, "When I confronted my husband, he said he didn't know who Tricianne Taylor was and that he did not remember getting married."
Mary additionally claimed that Tricianne is aware that John is still married because she had confronted the 60-year-old woman.
"She refused to talk to me, I wrote her a letter stating that John Witherspoon was married and had two children and four grandchildren. I have had no response. But she clearly knows now that she is married to a man who is not divorced," Reese's mother said.
