Thank you, this is very helpful.

1) Yes, this was one of the best things that happened to me.

2) Again, thank you for formulating that in such a clear way.

5) Yeah, nothing like that, luckily. No enemies I know of, no debts or hated relatives.

Your comment made me think in a refreshing manner.

From an external point of view you are just an emigrant with new personal and professional interests. Your old online acquaintances are not likely to care about your "retirement" except to wish you well or as a small loss; if there are exceptions deal with them individually.
