What if my husband, brother and daughter-in-law always look down on me?

Your husband's brother-in-law is jealous of you! People without culture have no self-restraint.

I don't think now is the time for you to ask what to do. Let your sister-in-law learn to respect your sister-in-law, after all, you are their sister-in-law at a young age! If she doesn't know how to respect you, you don't need to accommodate her. I think if you let him go, some people will think you are afraid of him. Will be more unscrupulous.

It doesn't matter if your husband's heart is towards them. You can also pull it over. I think if you and your husband can have a child, your relationship will be stronger. Children are the bridge between husband and wife!
