Check the quality time cube
If your wife is a big fan of quality time, find an easy way for her to let you know if you are giving her all she needs. For example, put a single die in the bedroom or bathroom. Have her regularly updates her satisfaction or lack of satisfaction about your time together using a scale something like the one below.
4=I need a bit more.
3=I need a lot more.
2=I need a lot more, and I need it now!
1=You don’t love me anymore, do you?
