Friends in society always drag you to dinner. I think he may have no intention, but he feels comfortable with you and wants to take you out to meet some friends. At this time, his initial intention may be good, because he thinks he wants you to grow up, and he doesn't want you to be so naive. If you feel unhappy at this time and your freedom of life is limited, you should talk to him.
Besides, he is always willing to take you to dinner. He also thinks that you are a friend he takes out. When making friends, many people choose to associate with different types of friends. Some people are suitable for talking, some are suitable for going out to play, and some are suitable for taking out to save face for themselves. Maybe you are the better one, so he is willing to take you out, because he feels that getting along with you and walking with you have a certain face.
don't think too much at this time, but mainly look at your usual friendship with him. If the friendship is good enough, I think it doesn't matter. What I am most afraid of is that many people are always hesitating about the relationship between two people, whether they have reached this one or not. In fact, the relationship between people is not so good after getting along, and whether the relationship between two people is in place. So we have to measure the relationship between two people.
don't think that the other person is a threat to you. If you don't want to, he can't make you happy, so you must learn to express your feelings. Whether you want to go or not, you must know what we are thinking now. I think the other person's next activity will change.
