Encrypted Morse code

I tell you my secrets secretly

Send a Morse code for you to read

You read it all and nod in acknowledgement

But only I know what I have revealed

I encrypt my Morse code

Don't tell you anything at all

I encrypt it with antonyms

And spell it the other way around

I wish you would know the hidden note

Know what is spelled in decode

I want you to know but I don't want to say it out loud

I wish you would decode my encrypted Morse code
