Just catching up on your thread. Your wife does seem to be very comfortable in her situation, and you’ve had some realization that maybe it will stay that way. Yet you still support her all you can, talk about her family, etc. I see little reason why she should come back to you now. She’s got the best of both worlds. If I were her, I might be very happy.
I’ve got a question for you. Have you met anyone interesting, some you might to go dinner with? It might put you in a different frame of mind and let her know you can play this game forever. At some point you need to get your own life too. Just my take.
