I don’t believe in vino veritas – in wine, truth.
At least not to the point that everything a drunk person says is true. Just imagine if that was an acknowledged fact: before witness statements at court you had to chug a quart of vodka and some beers…
I do agree that it lowers inhabitors and might access some thoughts or emotions that have been subdued, but not necessarily commanding or true. Like I might have days I hate my job, but others when I really enjoy it. If I gripe about my job when drunk doesn’t necessarily mean I hate it all the time.
The big issue I would have in your situation is the married the wrong people issue.
I suggest this:
Tell him that THAT comment hurt the most. If he wants to screw around with other women – your friends or whomever – that’s something he can do. You aren’t preventing him from doing it. But not as your husband. If he has this urge or need to do that then you two can just polish off a divorce as quick as you can and he is free to run around with his pants on his heels.
But… tell him that if he wants to be married to you he now needs to convince you that the past years haven’t been a lie. That his comment indicates he regrets marrying you, and he now needs to convince you otherwise.
He can do that verbally, but even better would be with ongoing actions and behaviors such as showing you respect, attention and love.
Tell him that you too can have doubts. They haven’t been prevalent in your thoughts, but his sentence makes you think that maybe your efforts aren’t enough, that for HIM you are lacking, and maybe your efforts would be better invested in another person. He shouldn’t worry that you cheat – you would never do that. But if you aren’t convinced that YOU married the right man and that said man was convinced that HE married the right woman… you might end the marriage.
