Interesting experience that fortunately does not seem to have left but learning. Social networks came into my life when I was already grown up and I think I was quite cautious in handling them, I mean Facebook, specifically, because in others I barely manage.
I have a very positive experience of a long-distance relationship with whomever I call, my unknown friend, with whom I maintained a relationship until the day of his death. He supported me in the process of quitting smoking and since he dedicated all his time to that work through Facebook, I dedicated myself to supporting him in his work.
Unfortunately, COPD disease took him early.
Social networks can be a very useful tool to connect with other people, but you can also find people who are not authentic.
It's good that you were able to find a friendship that benefited you a lot, helping you to quit your bad habit. I'm also sorry that he left like this.
As in face-to-face contacts, we must be cautious when placing our trust. And not let ourselves be dazzled by a fake or ill-intentioned shine.
{Success and until another time.
You are right, trust is not to be taken lightly.
