It seems like the OP is suggesting that the T should be constantly engaged or available, or else the T is withdrawn and abandoning the client. Or that time between sessions is basically time when the client is abandoned. But that seems like very black-and-white thinking to me. Like toomanycats said, an absence isn't necessarily an abandonment. My T is on vacation right now, so I'm not seeing him, but that doesn't mean he's abandoned me.

In any case, isn't this like most adult relationships? I have friends I see once a week, others once a month or even once a year. I have family members I see once every few months. The relationship is not severed because I don't see them more often.
