Disappearing and reappearing unexpectedly worked for me. I did that in response to W starting to disappear on weekends. I left early before she even had chance to think about her day. Sometimes I went to the park and read a book. Sometimes had early lunch by the riverfront. Sometimes I told her what I was doing sometimes didn't.
Although most of the time I was alone, I told her that I was out with friends but never mentioned names because she knows all of them.
It drove her nuts after awhile and she started to stay home and make plans for both of us. She made sure there was a plan early enough in the morning before I could unexpectedly get up and leave. It worked.
Now I am focusing on communication. I want her to be interested of what I am thinking but only if she inquires the info. She needs to be interested of that otherwise the info has no value.
There are so many ways to GAL but it's tough to break routines.
