All Doves will mate again in time. I would advise not throwing seed on the ground where it makes doves vulnerable to cats, and hawks. Place a tray feeder on a pole close to or under a tree for hawk protection.
Do not do anything with the nest. Most likely it will be abandoned.

help please im heart broken :( by: my mourning dove
I'm glad to see and hear your beautiful experience with your doves. I write to you with heavy heart hoping someone hears my, now lonely dove.
I've been throwing bird seed the past year out front and on occasion have had trouble with my neighbors cat.
After having animal control put a stop to it she's now letting it out again and it finally got one of my dove couple.
I've heard the one left behind calling all day around the neighborhood heart broken. We both are.
Knowing they mate for life and spend their life alone should anything like this happen, can anyone shed any light? Can I do anything for the one that cries all day?
Great Ideas!
