GAL is for you. If it helps DB your marriage, it's icing on the cake. Detaching will help you feel better about your activities; it'll also help you choose activities that will be more rewarding.
I know it's for me, but it doesn't make me happy. Maybe I'm just difficult today :P
Maybe it is the detachment that is causing the problem (or the lack of it, rather). But it's a process, you can't really speed it up, can you?
You know the expression, "Fake it till you make it?" I had the same difficulty, too. Everything I did reminded me of things I did with my wife and how I would much rather be doing them with her.
Just keep doing it. It does get better. Now, I look forward to Galing, and the painful memories are becoming less painful and less frequent.
I don't know that you reach "happy" so quickly, though. You find "fun," "contentment," and "distraction" long before that.
