Once we are faced with relationships that turn bad it's easy to remember that trust is like a paper once it's crumpled it can't be perfect again. Trust is a very tricky thing with any relationships, and people use their own defense mechanisms to survive lies. Once you meet someone you can be the person that trusts immediately, or you can be the individual that trusts by actions. Either way, you understand that once someone has broken your trust it's very hard to get this back. You will lose part of what you and that person had, and may never be able to straighten the situation.
Every good relationship is founded on the basis of trust and good communication. However, trust is vital because you have to believe that what someone is saying to you is true. That you can depend on them if times get hard, and that you know that they have your best interest at heart. In relationships, we often find that trust is one of the most fragile things that exists because it is nearly impossible to repair. Once someone has lied to you, unless you find it upon yourself to seek healing, you will never be able to believe them again. If you have ever seen a crumpled piece of paper straightened back out, you can see the lines where the wadding occurred. When you are dealing with trust issue in your life you need to understand that your relationship will never be what it was. However, that doesn't mean that you can't make it better, and you should always continue to strive for the best relationships with the people that you have in your life.
