My girlfriend always quarrels with me from time to time, and suddenly she will go and think about it. How should I solve it?

From your description, it seems that your girlfriend seldom misses you. A little wayward, a little immature, and even a little unable to live ... Personal suggestions are still divided. It's not like this. It's just that she's not suitable for you. You should find a considerate, caring and kind wife. Of course, you must be equally friendly to others. Love is not a unilateral effort. Only one party pays, so this relationship will not last long sooner or later. You will be very tired … don't waste any more time and give up looking for the next relationship.
