I get along with my father-in-law but my mother-in-law keep feeding him things about me, and then he also starts behaving rude with me. How to handle this?

Talk to your hub ... my case is FIL keeps poisoning my MIL and his relatives about me. 😂 over things i didnt do. I told my hub he did not believe, cos he sides his father. I tolerated, and things got worse as my FIL would yell and scream at me for no reason(he jus need to vent his anger on someone). My hub saw him doing it to me, and for once my hub sided with me. FIL nv dare to do it again. And my hub even caught him bad mouthing me over things i didnt do. My hub was so pissed with him. Now that i am pregnant, my FIL tried to speak to me. Which i fully ignore. My fren said i had a Monster in law 😂 My suggestion to you, never confront your MIL . Cos confrontation makes us looks like the bad person.
