Should i divorce my husband because of my mother in law?

Hi, i am a mother of 2, a girl and boy. I have had a roller coaster marriage since beginning, i even left my house twice. But came back for my husband. My mother in law is an evil lady she has troubled me a lot in the past but now matters have gone from bad to worse. She talks about sanskar and all but teaches all wrong things to my daughter who is 2.6yrs old. She pampers her to the extent of spoiling her and letting her do wrong things. My husband was in depression because of his earlier failed marriage and now has anger issues.. which i am scared will create a bad impression on my children's upbringing. Although he is educated, but still doesn't understand what his mother is doing to us and our family. She is an evil lady and cannot talk good about anyone. she interferes in my child schooling as well.. I cannot bear it. I love my husband but i am stressed because of her and i am unable to come close to him as well. But i feel like getting out of this hell hole and save my kids future. Also, my husband is the only child so we cannot stay separate. please suggest, should i divorce my husband because of my mother in law.
