The changes you observed and the physical ones you listed are great. I'd encourage you to do such things to see how they please you as well.
If there's one important lesson in all this mess for me, it is that my W fell in love with me when I was better as being really 'me', and out of love with me when I became very distracted by the outside. I'm noticing more attraction from her now that I'm doing things more for me again, re-discovering myself if you would.
Be sure those things are for you. If she gets pulled back to you b/c of changes you enjoy, then both of you will be happy, and the R will have much better odds to be longterm.
