The enabling/controlling discussion on that situation you mention is very hard to determine. A lot of really has to do with your reason. The line is thin, but there is a line to walk.
Let it go is almost magical to be honest....one day the pain is just gone. Hard to explain other than it happens when it is meant to happen and that is when you are ready for it. Some people never are and others never do though they will swear up and down they have. You will know it when it happens.....so just keep detaching.
