long time no see PG... May Allah

have showers of his mercy and Rehma on you forever.
I pray that if you are going through a bad phase of life (as I am assuming that from your post, may I be wrong!), may Allah

make things easy on you and make you pass this test for every second of life is nothing but a trial in this 'temporary' world. Yes, temporary world

...
As for your question, I do not have much to say because everyone has different experiences in life. Everyone is different. I, for one, find many great friends but then, at times I have seen many supposed-to-be good friends back stabbing me playing their two faced character as if they are some kind of cool Sherlock Holmes wannabe

... I believe at the end of the day, it's them who lose - lose the trust, credibility, and above all the status why humans are Ashraf-ul-Makhlooqaat...
Prophet

said:
"Human beings are made up of two small things: Heart & Tongue." If someone's heart is different than his tongue, then according to Rasoolulah

, they do not come under the true defintion of Human being... That should suffice against all kind of justifications people give for their rude/multi-faced behavior.
You and I and all of us should only TURST Allah

and keep our faith on Him alone for He has tested much harder His own beloved prophets of past.
Remember the hadith which tells us that there are only three friends of a person who remain with him even after his death.
"The best things that a man leaves behind after his death are a virtuous child who invokes Allah for him, a perpetual charity, the reward of which reaches him, and a beneficial knowledge which remains useful after him." (Abu Katada Hadith)
May Allah

have mercy and maghfirah for all of us. Aameen
