I have experienced people change on a dime, the totally unexpected, but maybe the worst is the sociopath who is a chronic liar. I think it is like 6% of the population is a sociopath. They always have ulterior motives. Once exploited by one of these creatures, I dont think life can ever be the same. Since, I have gradually isolated but another event caused led me to chronic isolation. It may feel good, but I dont think it is real healthy or the solution for me. I think at the root is not trusting self. I dont trust myself enough to keep myself safe when it comes to some people, and dont always know who those people are, and if I am out in the world and "living" and busy, then I could be too caught up and not see it coming, or minimize or ignore it. Intellectually, I know its irrational, but every cell in my body feels it when I try to talk myself into doing something social. I guess the question is, is it enhancing our lives?
