X Ambassadors - Unsteady Lyrics Meaning

If you watch the video (Unsteady, X Ambassadors)it shows a woman who's meeting someone at a place, a restaurant or such. Then, there's a father with his son. As they watch the kid playing at the table, the mother cleary there, the father pulls out a bottle of whisky, I think, pours it into his coffee cup(holding coffee) and then it flicks to the man and woman at a restaurant and the man pulls out a "flask" and pours it into HIS coffee and they "toast" and then he drinks some. I think the mom and dad of the son are gonna split, but, the other two are sorting out the addiction, and the woman, unlike the mom, is helping this man get through the addiction. The dad isn't getting any help and, probably, won't. But, if you see, the man at the restaurant is probably the son of the mom and dad, but older. So the son grew up with his father drinking, so he did, too. (This is a guess, that might be the son...)
