I strongly encourage you to leave your wife alone, get an individual counsellor, and throw all your energy into self improvement. Don't tie this to your wife's behavior or whether she notices what you are doing. You need to make these changes whether or not she wants to work on the marriage. And frankly, you're not ready to be a good partner, so take advantage of the time to work on you.
Do this ^^^^^^^^
Also, move back into the master bedroom.
Any tips on how to move back in. Let her initiate it or should I try and make the move? I will definitely ask my DB coach about this. I feel this is now a priority
