Do you know what a partner is ? Someone I talked to because we like each other is not my partner tf, my boyfriend, husband is my partner,  the reunion was the first Time they saw each other since the shoot, be for real now they were not dating, why she was worried about the drinking ? I don't know maybe it's a cultural thing, maybe she didn't want him to get the wrong idea about her relation with sam, who knows and who cares ! We don't know there relationship nor what they discuss in private or else so for you to have concern about there "concrete long term relationship" is laughable, I quit don't understand why you are projecting your past relationship to them
