Been there, 10 years, he went a week ago.
Firstly, all those names he called you? All bollocks, only designed to hurt you, to shut you up and to belittle you.
Challenge every name he calls you. You know your family love you. You KNOW you have friends. You know you are NOT useless at sex... but he's hassling you for it... IF that was true, he'd take it or leave it.
I used to lie and cover up for mine. The pressure NOT to let people see how he let me down. Then he told my friend's H a pack of lies, designed to make him ban our friendship. I just discovered he destroyed a much loved plant of mine today for no reason other than because it was mine and I liked it.
When he betrayed me to my friends, it was a tipping point for me. I realised that to make me look BAD, he had to LIE. For me to make HIM look BAD, all I had to do was tell the TRUTH. Once you get to this place, and let the veils fall from your eyes and everyone elses, you are free. The relief is astounding, the support and friendship you get is humbling.
Do you own your own home? if so, you can put a caution on the deeds and register your interest in the property. Collect all the financial information you can, statements, bills, etc. Birth certificates, passports, you name it, pack it. Get some money together.
Protect yourself as much as possible. Accept that your life has to change radically, and you may have to take the baton and run with it pretty fast to maintain normal family life without him, but the rewards will start to be felt immediately.
Please go and see the CAB and work out what you could be entitled to, tell them your fears of flight, and see if there is anything you could do to remove the risk of him flitting.
I'd also suggest you contact Women's Aid too, they will help you get out of the abusive situation and advise and support you, as will all of us.
Well done for starting this journey, starting with us. Please keep talking and we will be here for whatever you need, whenever you need it.
