Do use your dog as a common interest and DO use the dog as a way to communicate and to have something to talk about....
DON'T keep hinting and pushing counseling and such....(that is too feminine and isn't attractive and will come across subconsciously to her as weak)
DO let her lead on that issue. If she chooses not to bring it up, then so be it. You are in great shape because of what you have learned the past few months.
DON'T snoop anymore... In your case snooping now would backfire in a big way. I wouldn't chance it at this point. Remember, she may still feel that you always watch over her and snoop. Surprise her and surprise yourself.
