Why doesn't my friend like me?

I am very sorry to hear about this. I can't imagine how hard it must be for you. However you must know something....you are setting yourself up for endless grief and disaster, not to mention failure. Their unresponsiveness is a HUGE red flag. I would take that as an indication that they either just don't care anymore or they heard something about you that was not true. But since they are avoiding/blanking you I would simply cut my losses and move on. With friends like them who needs enemies right? And just don't talk to them anymore. Hang out on your own if need be, believe me it is a hell of a lot better than walking on eggshells around a bunch of immature brats who jump to ridiculous conclusions without getting all the facts. Ignore them from now on. Don't talk to them unless there is a dire necessity. Don't say hi to them, and don't sit with them. Don't share anything with them, and ignore all of their calls/texts etc. The fact that they choose each other over you shows that they don't care as much for you as you do for them unfortunately. Good luck :)))
