Thanks. I expect you are correct, that this will pass soon. That would make the most sense. I never asked for any of this to begin with. She volunteered it all, under no pressure for me. Maybe at the beginning, I filled some temporary void in her life. I will be bummed out if it ends bitterly though.
When I do visit again, I will be taking steps to make sure she is not feeling used. Hopefully when we move on for good, at least the memory will be fond. I feel that is owed, as some of what has happened will enrich me for a long time after we part company for good. I went into this hobby expecting just a series of short "all business" transactions. This situation has seriously surprised, and somewhat disoriented me.
