Hi,
I just read something during my lunch break that fits with what Theo said, "I think it will be the bomb of your willingness to leave him that will probably shake him out of his complacency":

**Sometimes it takes the threat of losing something to make you realize its value. Sometimes they need to walk to the edge to realize they don't want to jump. Until they feel compelled to leave, they may not realize they are happy where they are, and want to stay.**

I would add here that we may have to resort to pushing them. I guess this would be considered a LRT?
