i haven't got a clue what to say, I'm in the same position... and I've learned that you can ask someone's advice about your situation. even when you don't like their answer and you're not ready to listen today, you will keep it in mind and you'll know you're not the one who's gone crazy.. Just listen to your feelings and if you can't (for now)keep yourself and your child safe, keep all the advise in your head you're not the one who has lost reality... It's not okay that he hurts you in any way, words do hurt and, grabbing an arm is a step further... just keep yourself and your child safe
