They fought side-by-side in the besieged Azovstal steel plant in Mariupol, two Ukrainian soldiers among hundreds refusing to surrender.
And on May 5, Valeria and Andrew were married.
Three days later Andrew was killed, according to a Facebook post by Valeria on Wednesday.
The post included photographs of the two getting married in a bunker wearing their uniforms and photographs of the couple before the siege began.
The Facebook post — created on Wednesday night local time — also includes a message from Valeria:
"You were my legal husband for three days.
And for eternity you are my love.
My dear, my caring husband.
You were and are the best.
All I have left is your last name, your loving family and memories of a happy time together."
She promised him that she would survive the siege - and live for the two of them.
