Confronting my husband and what happens next?

Last weekend, after a drunken argument. I asked my husband if he had anything to hide from me and if there was anything he wanted to put on the table. 

This led to the next morning that he was betting again, he wasn’t in debt but he was gambling away money left right and centre. I knew this, I could tell by his behaviour of turning his phone towards him more, quickly swiping off things and putting his phone in his pocket.

For weeks prior, I asked if he was hiding anything and that he’s making me paranoid if not because he was acting weird, and he agreed I was paranoid and fed into the lies and made me believe I was going mad. For context, I’m 7 months partum to our baby and going through some post partum depression along side all of this so I really thought it was me and my hormones and generally feeling depressed. 

We had a massive chat and he told me he is addicted to betting. I didn’t ask about the money because it’s gone, nothing would change that so I asked if he had anything debts, loans, credit cards etc and he said there wasn’t any apart from the one I knew about. I now have access to his bank account which he willingly gave me and he is on Gamstop and is using this platform to find support. 

I’m looking for advice on how the hell to move forward, with trust, anger and the betrayal of it all.
