I don't think I need to call the person and tell them I am ending the friendship. I don't need that kind of drama and conflict. Once before I told him I was busy trying to find a job and secure myself financially and that is the truth. If he doesn't hear from me he will assume I am job hunting or working. He's semi-retired and has too much time on his hands and it is probably making his negative attitude worse. I'm not required to inform him of how I feel.
