try to be more understanding...
be extra sweet instead..ask yourself if what you've done for her before she was like that...
dont get too suspicious unless you have solid proof...
some women who liked to work are prone to behave like your wife..i am workaholic too and im doing it for the family..naturally il have to keep up w/ my competition to get to the goal and that includes a lot of activities that may sound suspicious for you..but unless theres confirmation dont push her or dont do anything to get even...
;love her more instead even if u feel alienated most of the time..she'll notice that and take time to slow down for you..my hubby cheated on me based on unfounded suspicions..now i cant forgive him for doing that...
