Status with the puppy :(

I apologize in advance for a bit of a sensitive post.

Although the puppy from the previous post peed and farted everywhere in the home, from spending almost every hour together for a week, I fell in love with her.

...
Guess what, the previous owner came back from a trip and decided to not put her up for adoption.

I was upset, but what can I do right?

I gave her back to the owner because I figured longer I have the puppy, it'll be harder for myself.

The last 3 days have been very depressing. The home is so quiet now :(
