My sister-in-law has never had my contact information. Is it too embarrassing to provide it?

I think this is normal. It's just a way of contact, and it has nothing to do with face. Think again, you married her brother, how can you be an elder? It is not normal to give her your contact information. How can you care about these little things in life? You'll be exhausted if you care so much.

And under normal circumstances, they are already in love with each other, and they should have been in contact for a long time. Maybe others feel that they are asking you, and you may not be willing to give it. You offer it yourself, which shows that you are generous and decent. At least your sister-in-law will have a good impression on you, which is the basis for you to get along with your husband's family. Friendly relations with your sister-in-law are very important. If you annoy her, it will definitely affect your relationship with your husband. Not to mention getting married, you should get in touch with your boyfriend's relatives before marriage, know more about your future husband's family, and find good allies first.

My roommate is really a winner in this respect. Her boyfriend's sister is in our class. When his partner is internship in another city, he often asks his sister to visit her and give her something. At first, his sister was often entrusted by her brother to deliver things to her in our dormitory, and then she would come by herself. The two of them get along better and better. They often go shopping and eat together. People who don't know think it's her sister. We all said she was really good. She got rid of her sister-in-law before she got married. Getting along well with your boyfriend's sister can also enhance your relationship with your boyfriend. Many boys will worry that their girlfriends will not get along well with their mothers, brothers and sisters in the future.

From ancient times to the present, besides the contradiction between mother-in-law and daughter-in-law, there is also the contradiction between aunt and sister-in-law. In addition to the mother's feeling that her daughter-in-law robbed her son, his sister will also feel that you robbed her brother, who generally likes her sister very much. Once my brother has a girlfriend or gets married, my sister will definitely be jealous. If you don't even give her contact information at this time, it may make her feel that you are not easy to get along with.
