I look at it this way would you rather walk around without your gun to make her no feel weirded out or do you feel there is no real reason you got a ccw anyway??? I would much rather carry and know you and whoever you are with is safe and maybe weirded out then not carry and need it one day..
Also I to vote dont see dont tell what they dont kow cant hurt and if they find out the hard way they will be thankful for it.. That goes for friends and girlfirends abroad
