When people fail you, do not be too fast to conclude they ain't loyal, atimes it is circumstances that made them not to fulfil their promise or when you ask someone to do something and he/she didn't, think before acting, look beyond what you see..
You see that boy you gave an homework that didn't do it, he was being maltreated by his step mother not that he is not studious or lazy
That person you lend your money that refused to pay back at the right time, he had to use your money to save her Mother's life who had an accident.
That lover of yours that break up with you for no reason contacted a disease and doesn't want to destroy your life with it.
So let us delay in passing judgement on people because of what they didn't do, we really don't know what is going on in their life, let us give them time to explain themselves.
Patience solves all problem
