I'm happy to hear that you're doing the GAL. I hope that the cinema was enjoyable.
Your wife says that she doubts that you appreciate her. Appreciation is an action word. Therefore, without "pursuing" her, what could you do differently? Well, if she speaks about her boss, use active listening whether you agree or not. Also, give her space, and help around the house.
I commend you for not reacting upon seeing OM2's gift. You did a true 180!!! The 180s may not "feel" comfortable. However, it helps in turn-arounds, and prevents confrontations. When you do the 180s, your spouse is bound to take notice. Therefore, keep the changes going!
