The thing you need to concentrate on above all else is.....
Yourself.
You are the linchpin and it's vital that you do this. Everything else depends on you being in the best possible form.
The other "stuff" patience and forgiveness are tools you use from yourself. Does that make sense?
How about - if you are "in the zone" it's so much easier to practice the other "stuff".
There's probably a reason why his things are still there. My W did the same thing for two weeks. I have a feeling that she was so unsure at the time and then something else went off in her head. No idea what. And then to my horror at the time, collected everything.
Don't rush things.
Everything comes to those that wait. NOW kick in with patience.
