The first reason is that he knows that there are many handsome fitness instructors and many fitness men in the gym. He is not confident in himself. He is afraid that if you go to the gym to see the body of a fitness man, you may dislike your body. Men's self-esteem, this is understandable.
So what you need to do with this kind of problem is not to quarrel with him. Although his reason seems a little naive, it is also a sign that he wants to monopolize you and love you! You have to be persuasive, let him go to the gym with you, and let him have a charming body with you. So he won't say anything!
Second, he may think you don't need to go to the gym. In this case, your boyfriend doesn't know what your own mind is, so at this time, you should tell him that you go to the gym by yourself to have a healthier body, and you also want a more fit body to support you. At the same time, just saying it is not enough. You need to give play to what girls have the most advantages-coquetry and admiration. You know, a normal boy can't resist a girl's coquetry, not to mention he is your boyfriend. He will definitely agree to your going to the gym.
Another reason is that he doesn't want to spend the money and let you go to the gym. I always think that a boy who doesn't spend money on girls can never be a good husband and father. Girls don't have to spend a lot of money on boys. Some girls even earn more than their boyfriends. What girls want is the attitude that boys want to spend money for their girlfriends. So if your boyfriend thinks so, don't ask his advice at all, and pay for the gym yourself.
Therefore, when solving the problem, we must first understand the cause of the problem and then prescribe the right medicine.
