Cate Edwards is tying the knot with her long term boyfriend this weekend, but without her beloved mother by her side.

The pretty brunette daughter of John and the late Elizabeth Edwards, who passed away on December 7, 2010, after a six-year battle with breast cancer, is marrying Dr. Trevor Upham at the North Carolina home her parents built, and she spoke lovingly of her mother and the wedding plans they made together.

“In the year since I said goodbye to my remarkable mom, so many things have changed,” Cate said in a heartfelt article she wrote for Glamour magazine.

“Many of those changes—like my upcoming wedding—were rooted in the days when she was still wonderfully, mischievously alive. On the Friday after Thanksgiving 2010, just before we learned that Mom’s cancer had spread to her liver, my boyfriend, Trevor Upham, surprised me by flying in to visit my family in North Carolina.
