Dito, the way in which your dh responds now will speak volumes.
If he is genuinely remorseful he for one shouldn't be the least pissed off about his precious whiskey, how bloody dare he be annoyed about that! That should be the least of his worries.
He needs to be honest and open with you now. The problem with this is all the lies that he's told, makes you wonder what's real anymore. That's where RL support pays dividends as apposed to online support. Your friends (I presume) will know your dh far better than mn. Even though we can of course guide you through the utter devastation, we don't know him as you and your friends do. Is this totally out of character etc...
I don't blame you for not wanting to open up to RL friends, it feels almost like you're betraying your dh trust, the person you love/d. It's a complete mind fuck! Once you do though the relief is immense. I will be forever greatful to one great friend of mine who listened and helped me far more than she will ever know. She didn't judge my decision to stay, she helped me to realise that I could get through the devastation whether we stayed together or not.
The most important thing in my case though was the way dp acted once he'd confessed. Since then he's not lost patience with me, not once. He's been remorseful and full of regret, he will talk (even now 18 months on) whenever I feel the need (which is not so often these days). He's changed as a person and isn't the selfish, self centered twonk he was during that time.
Don't make any decision until the fog has lifted and you can see more clearly. Whichever decision you make is right for you. Take each day at a time, you may have a better day tomorrow and then take a step back the day after. Be prepared for this. Each day you will be getting a little bit stronger (even though at the time it doesn't feel that way), when you look back you will see little turning points. You'll have brief moments of it not being all consuming, the images you see every moment will become less frequent.
You will need to talk to your dh. Come back to us when you have.
Take care
