Victim blaming?

A little backstory. I’ve been with my boyfriend for 4 years and we have 3 kids together and I’m pregnant again. He’s been nothing but emotionally abusive and manipulative our whole relationship. Seems like it gets worst with each pregnancy but I just can’t leave. He controls all of our money and guilts me for being a stay at home mom with no income. My parents keep blaming me for putting myself in this situation and telling me I’m weak for not leaving. They want me to come back home but I just can’t leave him. Every day is hell but I feel obligated to stay for so many reasons. How do I get my parents to stop blaming me and accept this relationship.
