LovetheHub, thank you for your inputs and advices.
Yes, I'll keep following DB and trying 180. Right now, I think I made some changes but my H didn't notice it or he claimed it is already too late to change. We kindly agreed to delay the discussion of D/S for one year. But since H is more and more into that OW now, I'm not sure if one-year delay will make things better or worse... Any opinions?

Thanks,

H moved out in 11/2013
