Evidentally I was wrong. After thinking about it more, I realized that what I thought I needed to do was actually just doing more of the same. Plus, he's not ready to commit to R and wasn't really ready to move back home. So, he moved out again (he said he was going to his mom's) and I have "gone dark." He can only contact me if it has something to do with the kids. I even changed the locks so he can't come in whenever he wants (cake eating). It's only been a few days, so we'll see how it goes.
