Fake Friends

Fake friends? what is the mean? I also do not understand what is meant. But I think it's fake friends who only close friend at us when he's wants, when she really need our help when there is no longer a friend who would help him. Nowadays a lot of people like that, come when needed but when he was having fun with other friends? what did he do? we just forget! But when he was feeling lonely when left alone by his friends to another, what will he do? of course he will come to you, haha bstrd! When he has something that makes him happy, he did not tell him what makes him happy to you, he just said "oh my god I'm happy to not have thought of this happening" and what did he do after that? looking for friends whom he considered his faithful friend and told him everything in detail what makes him happy and leave us just like that. Fake friends are truly friends asshole, fuck, shucks or whatever !!I really, really hate this. because there are so many people like that around me. Friends say it proper? when it comes is needed, then leave when it was getting what he needs ? Friends say it proper ?  when he was happy, but never shared happiness is to you ? Friends say it proper? when he went to have fun with other friends and did not invite you, even though he had planned it and he knows that you know his plans with other friends, but do not offer you to join with them ? Oh my gosh this really makes me sicken !!
