Hi,
I'm new too. In a very very similar situation. However I have let this go on for many years now. I'm now stuck in a marriage with an alcoholic and the ONLY reason I'm still here is for my younger 2 children are 10 and 11. They would be heartbroken if we split up as ive always managed to hide his behaviour from them. If I could tell my younger self anything it would have been to walk away when they were babies, so they would have known no different. Sending hugs
