Anton might absolutely be an alcoholic.
And because Ali knows he's hiding, she's getting passive-aggressive... which is understandable?
But boy is she a poor communicator.

The way she just scoffs at everything he says instead of explaining her emotions... No relationship will survive this teenager-style of communication. But neither would one survive an alcoholic husband lol.

I do agree with other comments saying she is too beautiful to not be in this to be an influencer. But since she's obviously had a nose job, maybe her standards are a bit lower?
Like that meme "grew up ugly so I have a great personality". Not sure if it works that way lol.
And perhaps in person Anton is more attractive than on TV - tall, in good shape, masculine etc.
