There is nothing healthy about holding onto 3 inches of damaged hair just to prove your hair is long. Length doesn't always equal healthy hair. On average most people should get regular trims every 3-4 months, unless you spend the majority of your time in a protective style like a weave. For those that prefer heat free styling this is just as important because the use of water and styling products in your hair often cause the hair to swell and contract which can also cause split ends and breakage.

The longer you hold onto split/damaged ends the more breakage will occur and the more hair will probably have to be cut off when you do finally decide the get a trim. Split ends don't just break at the ends of hair, they can cause damage higher up in your hair causing it to look thin and sparse. Once ends are split nothing can put them back together. Even though a good strength or deep conditioning treatment can help hair look and feel healthier, it does not repair split ends. A good way to tell if your ends need to be trimmed is if you can see through them clearly, it's probably time to let it go.
