Sorry to hear you are having such a frustrating time. From what I have read on others' threads this seems to be entirely normal when a spouse moves back in.
As for letting your spouse know what YOUR LL is - I haven't found a way to do that (yet). Maybe when she does something that makes you feel her love for you - let her know how good that makes you feel.
On the other hand, for now, if you can see her showing love for you in HER LL then at least you know she cares but just isn't bi-lingual yet
Anyway, hope you can find the continued strength to get through this stage of piecing.
