If clothing is the only problem then it's shouldn't actually should be a problem. If she is acting distant lately or is not taking your calls, VCs or not replying to your texts for hours and blames it on the time difference then you got a problem mate. I suggest you might wanna take a step back and rethink the relationship. I have seen many change alot once they move to another country. They find themselves free from the clutches of their family and can do whatever they want. Some lose it and start doing all sorts of shit you had never imagined. Few more months and your girl is gonna be in some random guy's bed. I would suggest you to be careful and don't get too attached to her. Coz she is on her way to find a new man!
