How to refuse brother-in-law's kindness? It really shouldn't be good.

You can see from your last sentence: 1. You also like your brother-in-law a little in your heart, at least you don't hate him; 2. Your character says that what you like to hear is kindness, but what you say is weakness. You are always a little entangled in letting you refuse directly, and you don't know how to refuse.

It comes down to your character. Say no decisively, just tell him and tell your sister if you harass again. If such a man ignores his wife's thoughts, it is estimated that others are not much better, at least he will find another woman, without a man's family concept and sense of responsibility. Personally, I think your brother-in-law is plotting against you and trying to occupy you. Don't listen to your brother-in-law, I love you, I only marry you because I can sleep with you, and there is also a man's desire to conquer. In fact, if you think about it a little, he can't marry you even if he divorced your sister. According to your personality, you should consider your sister's (your sister is good to you). If you divorce your sister and marry you again, at least your parents may be furious. I think it will be really messy at that time. Your sister can't stay at home. Relatives are the most important.

Personal advice, I hope you can get out of your troubles as soon as possible.
