Hello Dear @turpsy
I think the same could be said about close friends Turspy. But I haven't seen any research on that :P
I am sorry to hear you have been trough such disappointment really. Sometimes, it feels as if life doesn't give a break! But, I am truly glad to hear you have been able to manage your frustration towards the person in a healthy way. Also, thank you for sharing with us your strategy for dealing with it. Forgiving and focusing on something else, that is positive is a truly healthy practice for your mental well-being!
All the best to you my dear.
:)
Thank you. Igualmente.
