Am I wrong for feeling the way I feel ? I dessagree with my wife wannting to go out every wk-end to the club.

I work as a contractor overseas in a war zone enviroment while my wife is going thru this phase for the past month of going out with her friend to the CLUBS!Wher guys always buying her drinks and she even went as far as innitiating a phone conversation with some stranger who she exchange #'s with !I think she's married and we have two kids and a the Club life is more for single woman looking for men ! We are going thru really tough times right now that she makes me feel that I have no right to tell her that she shouldn't be doing that ! we always argue and fight over the phone over it !
