 Sharaf writes that Reich 's personality changed after his experience in Oslo . He became socially isolated and kept his distance even from old friends and his ex @-@ wife . His students in the United States came to know him as a man that no colleague , no matter how close , called by his first name . In January 1940 he wrote to Lindenberg to end their relationship once and for all , telling her that he was in despair and that he believed he would end up dying like a dog .
