I told my wife am travelling for business meeting but this happend

I got married to my wife last year
and since then we have been
living happily. From time to time i
always travel far from home for
business trip and sometimes upto
5days before i return and my
wife has no problem with that.
Few day ago, i lied to my wife am
traveling for business meeting
and i will spend a week before i
return and she said agreed, little
did she know i was going to meet
a lady i recently met.
Instead of business meeting, i
visited the woman i met in my
last visit and i took her to a hotel.
On the third day i saw something
that shocked me, i took my new
lover to a cinema.
while sitting i saw my wife resting
on the arms of another man
having fun.
Am very confused, should i
approach my wife while i have
another lady with me instead of
going for the business meeting i
told her. What should i do.
