You’re right, relationships with parents can be complicated. They say ‘hurt people, hurt people’. It sounds like he doesn’t know how to manage his own emotions and takes it out on you. And it’s normal to need emotional stability from a parent. As hard as it is and as sad as it may feel, it’s important, especially when in this kind of situation where you can not count on the parent for emotional regulation and stability, to learn to do it for yourself. Maybe stress your boundaries and needs again & maybe you can get up and leave if he’s being aggressive or emotionally abusive if he won’t respect your boundaries. Sending you a big hug 🤗🤗
