The Talmud , Yevomos 63a , on the last line , teaches that Dayeinu can save a persons marriage ! 
     A spouse has to always work on appreciating the many ongoing benefits they receive from each other.

  & she saves us from sin etc. Etc 
 You can add 100 more items to this list & you will be a very happy person !! 
Now may be a good time for a gem of Torah study.
