Very annoyed with old best friends?

I'm going through the same thing, you're annoyed easily with them because you met someone better, if one thing annoys you about a person everything the person does will start to annoy you, here's a thought how about you tell them straight forward what you just told us, just go tell them walk away and continue life with your nice friends. good luck you have nothing to lose, except a couple of annoying people, hope I helped. :)
