Secondly, of course, he chose you, which means that you are also very attractive to him, which means that you are also excellent.
So cherish the feelings between you. Actually, you don't have to worry about his feelings for you. As for his loyalty and disloyalty, it has nothing to do with his appearance. Communicate with him well and explain your thoughts. In fact, you are only angry because you are afraid of losing him. You love him very much, but if I were you, I would be smarter and more confident. Let him and people who like him see a confident self. Don't always quarrel with him, or you will blame yourself for really losing him.
Don't worry about tomorrow, just grasp today.
Come on, I wish you happiness.
