I have to agree with Robert/Chong/Hajo , if it's Business , she will act as she needs to do . If it's a Family thing , you are not yet included into those kind of matter's , until your married to her . So do relax , give her some space . Think if she was with you in your Country , by herself , and you would be getting phone calls all the time , from Women or Men , it doesn't matter , her knwing the western way's , would it not make it even worse for her , being in that kind situation ?
I am sure , she will explain it all to you , when the time is good . Don , and more important , it will make you look better in her Eyes , to be so understanding .
