Standing up and saying out loud what has been done to you is such a huge step. that first step IS the hardest to take.
You can't live like this, not happily love. your DS is amazing to want to help get things on a safer keel for you, but he shouldn't have to if you see what I mean.
Please stay with us, keep posting and we will help you find your inner strength, your bravery to get to a safe place and leave this dreadful bully behind.
You need to report the threats to kill. seriously.
Even my x didn't threaten that. He used to write lists of my sins/misdemeanour's apparently. People WILL take it seriously, even us who HAVE been with nasty violent men will take you seriously, it's bad love, really it is.
You deserve so much more from life, and you will have it, but you have to find the exit.
We'll be with you all the way.
