Just wondering...

I read a couple of times that quite a few people would rather leave therapy first when they fear they're getting too attached or that their T might 'abandon' them (even if it would simply be by going on vacation).

What do you think this is all about?

Trying to avoid abandonment by being the first to walk out?
Trying to show yourself or your T that you're strong enough to handle this?
Rather blaming yourself for leaving than being stood up?
Choosing the short pain?
