How to say goodbye.

We all know full well, when the time has come to say goodbye to that secret love.
All sorts of things intervene in a clandestine relationship to put pressure on it, and eventually, it becomes unbearable. Life is miserable, and it's time to move on.
So, how to say thank you & goodbye may not really convey your true feelings.
An email, well that's downright cruel, unless you hate the person so much, you don't care about upsetting them even more.
By far the best thing in my opinion, is to go out somewhere quiet & peaceful. A park, river bank picnic, or a long walk in the countryside. This way, you can say your goodbyes calmly and with a good explanation.
Once you're done explaining & it's time to walk away, you could give them a card with some nice words in to say what a great time you've had with them. Let them down gently & with some dignity.
More than that, leave your secret lover with nice memories of parting, not those harsh words that never heal in the mind.
