She knew what she is getting into so why is she mad now?

-Because She didn't know what She was getting "Into"- & She's Blaming YOU- for finding out !! :( So Here's your Choice: Promise Her you'll Retire from the Service when your current Tour of Duty is Up ( and DEAL with It- in the MEANTIME). OR- Break off the Engagement, & get ON with Your Life ! Whichever Choice You Make, choose the One that's BEST- for YOU !! Good luck.
