Choosing to form a relationship with a pet is like signing a contract, giving you a few years of joy followed by the sorrow of loss, which although increasingly diminishing, will last you forever. You make a gamble, betting that you are mentally prepared for that loss.
The more you invest, the more you loose. And you will loose.
The teachings of life, how enticing. But what would be the right thing to do here, provided you have the will to choose for yourself?;
Forget about the past to better live in the present?
Or cling to the memory, living in anguish?
Either answer is cruel in its own way, as is choosing. Is it even the right choice to form the relationship to begin with?
The answer, in my opinion, is rather ambiguous and therefore not something that should carelessly be conveyed.
But I do hope that you find a way to move on, or not, as long as you impose clarity to your decisions.
