Songandance has/had a clinger too - I think he recently moved out after 2 years. There are more, I just can't remember everyone's situation.
Mine is definitely a clinger and has been since BD. Clingers show that they "need" the anchor perhaps more than most and this is why it is important to GAL as quickly as possible and as effectively as possible so that they see that you are able to function quite happily without them.
Sometime it is very difficult to detach especially if you choose believe that because he is a clinger he will change his mind and want back in.
The clinger keeps you dangling for as long as you let him. The clinger still believes that he is entitled to "his life" and that the LBS has to tolerate what he does because he "doesn't want to hurt anybody"
I sometimes think that the clinger is also more Naive than the leaver. They honestly believe that they can have the best of both worlds. They have to keep connected because of the children, the pets, the bills the house, the goldfish but NOT the spouse!
Clingers are exhausting because they never give you a break and a chance to detach. Your feet become hardened to all the eggshells you keep walking on. The LBS becomes too wound up in noticing the teeniest of details and spends a lot of wasted energy thinking carefully about every word and nuance in the conversations.
The clinger is devious and pathetic at the same time. The clinger knows how to manipulate and because you get very few chances to detach the clinger knows how to continue to push your buttons and ironically keep you clinging to him!
