Your husband is thinking of himself first and not his daughters first which is so sad. He wants an easy and cheap divorce so he's using intimidation tactics to get you to comply. He's even blaming you for asking to secure your daughter's future! That's so wrong! I feel so sorry for you being subject to this hostile behavior. I don't know. If I were you I'd probably say something like "I can't speak with you about this when you're trying to intimidate me. We can either talk another time when you're calm and rationale or we can go through lawyers." Then walk away...
To me it seems separation is more important right now than divorce. Your husband needs a chance to cool down before he's in any shape to go through with a divorce. Is there any chance you can take your girls away for a two or three weeks? Could request emergency leave from work and take them back to your country to visit your parents? Or on a vacation to the beach? Or stay with a friend? If you could just get away for a while I think you'll see a change in your husband.
