Perverted father-in-law constantly harasses his daughter-in-law until he is satisfied

An unreliable father-in-law, who often contradicts my mother-in-law, has rolled into our house. My father-in-law has bad habits and is messy; I didn’t like him at all the first time we met. He just sat there while I felt uncomfortable and wished he would leave as soon as possible. My intuition was correct.
