He left me with 3 kids 😭

The worst thing happened today. After my partner spent months drinking all our money away for i told him he needs to stop to afford xmas and to afford bills etc and he says he doesnt want this life anymore. He doesnt want to be a dad and he isnt cut out for it. He wants his freedom and to drink as much as he wants etc. We have been together 9 years and have 3 children together. Our whole relationship he lied and spent all our money. I sacrificed heaps for him because he kept saying he wanted to change. So i wanted to support him and make him the dad i know he can be. But years go by and hes worse than ever then just says he doesnt want to! I wasted all these years building a life with a man who was never going to want us 😭😭 he was amazing for the first 5 years. right before xmas! And he has no money to buy them any presents either. Which means i have to. I need to hear from people who have experienced this because im broken and need to know im going to be ok 😭😭😭
