Have all the female students studying abroad married foreigners after graduation?

Not necessarily. Your girlfriend's going out will broaden her horizons and she may start thinking about your future. Women usually think so. So, if she goes abroad, there is an 80% chance that she will break up with you. Good feelings will break up after going abroad. Really, there is a distance when we are apart, and I know it very well. Brother, I advise you to relax. If you really like her, you don't want to break up unless you catch up with her abroad.
