I guess it all boils down to if YOU are TRULY happy with the current arrangement. Are you placating your wife?
When the arrangement began, I was not happy. I missed her, I missed my home and my daughter. When I originally moved back there was tension and anxiety on both of our ends. Turns out, we weren't ready to be together. We still aren't. The holidays were the worst because I had nowhere else to go and therefore we were sharing the house. Her presence bothered me (like I was going to pursue her) and when she closed her door to "go to sleep early" (OM2 phone call), it made my anxiety worse.
I'm not placating her. Her emotions and moods do not affect me anymore. She was very grumpy this morning. I was cheerful. She does not like me now. I...don't care right now.
