You have your charm. You have no choice but to feel good about yourself and be good to her forever. Don't take her away, she is not as good as before. Girls are very sensitive and have a strong sixth sense. So she can feel your subtle changes. Your girlfriend wants to lose weight, which means she wants to be more beautiful. Maybe he feels a little inferior, because he is a little fat. Maybe he thinks you are too handsome. She wants to be more beautiful to deserve you. Whatever the reason, I mean, it's also a reflection of your girlfriend's ambition.
You can't stop her from hitting her, but a healthy and normal way to love her should be to help each other. Thanks to you, everything is fine. You are worried about gains and losses, and you are also worried that the other person will get better. Your mood is obviously wrong. I suggest you exercise yourself and don't worry about others leaving. The love between two people is the joy of each other's willingness, the emotion of empathy and the result of fate.
It has nothing to do with looks or family background. If you love someone, you should give him some space. If you are in love, you have enough fate, she will never abandon you, even if she is beautiful, you are as ordinary as grass. If not, even if she is fat, you are as beautiful as a pot. For you, it feels like you are looking up, but for her, it will look down on you and hurt your self-esteem. Such a day must be unnecessary for you, so if she really wants to go, let her go, let your beloved have a better home, and let her go when you should let go.
