I would expect you have one and off days of sadness for a while. You are mourning a loss. I have up and down days/weeks. And like you even with my D7....I was at dinner the other night with her and got really sad seeing the families together with the moms/dads together and got sad for D7
Its tough and I can only say it may just take time before that subsides. It seems some WAW do wake up eventually and many too late and some never. I don't hope for it and think it would be super difficult anyway to go back. At least back to crazy town....
You are 2 months out since WAW moved out so give it some time my friend..it will hopefully get better. I start my solo journey this weekend and I am sure the loneliness will give me more ups and downs too.
