Disappointing Disrespect

It's the second time. The second time I trusted them and they let me down. They apparently don't care about our friendship. They blatantly let me down and are now pretending like nothing has happened. Well, I will be civil and see them once in a while, but they aren'y worth my time. People that pull you down over and over are not worth it. I've tried and put in the most amount of effort, but I am exhausted in every possible way.
