I think you should feel very happy. He is not sociable, but that doesn't prove that he won't. He managed to get married with his girlfriend, which proves that your husband is sociable, but he may not like to get in touch with outsiders. And he sticks to you with you, which proves that he really loves you. If you want him to be sociable, you can enlighten him and help him. The premise is that there will be no contradiction because of his interpersonal relationship.

for most women, husbands are too sociable and not clingy. Always socializing outside and enjoying being with friends, wives often have worries and doubts because of their complicated interpersonal relationships. There are two kinds of people I know around me, such as those who are particularly sociable and don't stick to their girlfriends. They are basically central air-conditioned and have a good relationship with everyone, especially the opposite sex. Even if their girlfriends are present, they are unscrupulously flirting with other girls. It often makes his girlfriend feel very insecure, but he thinks it doesn't matter and thinks it is normal interpersonal communication. But this kind of boy, like the one in the question, is not sociable, but he is very attached to you. It can be judged that he is probably a warm man type and an air conditioner, but he only warms you. And a boy is willing to stick to you, which shows that he really loves you. Imagine that if you are with someone you don't love so much, you must be eager to find an excuse to go out every day, and why do you want to stay with her all the time. If your boyfriend really has a good interpersonal relationship, I'm afraid you will start to worry that he will be ambiguous with other girls again.

There are many people who live a casual life, that is, they are willing to stay with the people they like, rather than taking the trouble to establish and maintain a false interpersonal network. When they meet friends he thinks are worth making, he will show amazing interpersonal skills.
