To Trust or Not To Trust?

5 letter word, so easy to say but to actually trust someone is so much harder. It takes ages to build but only takes a second to destroy. And now people I used to trust try to merge back into my life (or what’s left of it). What should I do? Let them back and risk to lose everything again once things get a little difficult? Reject them and stay  on my own? Could I trust them ever again? Will I miss out on a life I once had? Can I count on them to get me through hard time knowing they’ve already failed last time? Will I ever be able to call them  »Friends » again?
