Wow, it sounds like we are in a very similar phase of all of this. I haven't heard an ILY for months and months now though. That running they do, it is from themselves and their issues, trying so desparately to find happiness. It is so hard not to take it personally though.
It is frustrating that they just can't see it, especially when they seem so "close" to the way they were. My H seems so much like himself yet we still live very separate lives right now (absolutely his choice). So he is still out there.
