I think that is very positive to move slowly re: moving back in. My H did not leave our home during our M problems so I am not a wealth of info there but will give you any input I may have. I am glad to see you focusing on correcting issues with your R before moving into together. I will be watching to see how you address this as I think most Rs need to be able to address issues and not avoid them. Well, enough rambling...I have tons of work to do!
Take Care, SP
According to the Buddha, praise and blame, gain and loss, pleasure and sorrow may "come and go like the wind," but happiness comes if you can "rest like a great tree in the midst of them all."
