I think it will last because you are opening up to him now but of course it will need repeated over and over until it gets ingrained. That's normal.
Also, since you struggled with this too-this is an example how it must be the client who comes up with the insights rather than the T telling you notable observations. I pointed out your guilt weeks ago, but it did no good/was not helpful. These patterns have to be experienced with your T and in person for change to come about.
Sounds like relief coming from you.
