Nobody has picked up on the 2nd gun in the dresser drawer. He knows his wife could have another, maybe better, life without him. The gun in the closet gives his wife the option - she can use it on herself to leave life altogether, or use it on him to start a new life. The second gun is for him to use on himself if she chooses the first option.
It's a love song and their love is unconditional.
