I emphatically second that motion!
Apparently, this priest was a drug user before his conversion. Addicts are never really former addicts. They are, at best, only in remission. And addicts are very manipulative people. The whole way this is stated - about how he is being thrown away like rubbish and perhaps he deserves that - is calculated to cause a reaction of compassion. But although he is very specific about his feelings, he is very vague about this situation.
The present complaint that you have heard about is, as far as I know, from the one person that I can honestly say I did more to help and support than any human being in my entire life.
Hmmmm. That does sound like a close relationship - probably with another person who had problems similar to his own.
