Spend a lot of money to find the golden idea of love ~ ~ think you are resourceful and enterprising

Judging from your question, it seems that you are still a student and you are asking strange questions. . . .

1: You think your boyfriend is too thin to force him to eat hard food. It's not like raising pigs and fattening them. . . You can ask him to do more physical exercise, run, play ball, and do 50 push-ups and sit-ups every night. If there is a playground near his home where you can do pull-ups and parallel bars, after all, it is much more handsome to build a strong and fit muscle than to keep a fat figure.

2: You are always quarreling, he must be impatient. Quarrel is the catalyst of love. A little temper will make your boyfriend cherish you more, but he can't stand it if you keep doing this. You pay more attention to him consciously, and let him see that you care about him deliberately. Slowly, he will be very touched and your relationship will be sweeter. Then play a little temper at the right time, so it's not easy to fight or sweet.

It is up to you to change your personality. No one else can say anything. Only you know yourself best and your shortcomings best. Think of overcoming your shortcomings as a contest between yourself and yourself, so that you will be more motivated and easier to correct your shortcomings.
