I don't know what to do.

Hello, as a brother-in-law, he can't tell you what to do with your work and life. Tell you where to go, and you must go there. Maybe you don't like his suggestion.

Judging from the above picture, I think you have your own ideas. There are some things that you can handle, and you can solve them yourself. Because he is not easy to intervene as a brother-in-law. If you really want to ask. You can communicate with your sister first.
