Secondly, your girlfriend must be a master of showing off. She brought you a diamond ring and was shown off by others on the spot. I went to identify it and found it was fake. Become angry from embarrassment and break up with you.
Do you really want to spend your life with such a girlfriend? A woman who can't stand the blow of a fake diamond ring will betray you for a diamond ring given by others after marriage? This is worth thinking about.
Running to identify it fully shows that she doesn't trust you. And greed for vanity. Such a poor woman, life is boring, find a girlfriend to find a wife to find the kind that loves you. Looking for such a person, you will feel tired and don't know what she is thinking every day.
