Notice the people who are happy for your happiness and sad for your sadness..
Impolite as the language might be, its very true-ironic. Wanting things to be better, trying/wanting to help, bringing them out, leaving-they get offended after how they acted, in defense mode, try to justify/blame/hurt you more. People like this are sick cowards when they trash someone/what's most important in their life.
never stop...how true this is. Even if they are only friends, never stop saying how much you love them. For, some today they won't be there and you will never forgive yourself if you don't tell them how much you love them
It isn't so easy to forgive yourself for misplaced trust, but of course to be free of the thrall of manipulating deceiving users is worth it.
