>>3122032It doesn't go into details but Joseph says Robert hit him up for sex. Robert doesn't specify who started it, so it's possible Joseph did and seduced him, though they're both kinda slutty so I think Robert approached him first. Also you see a pic of Robert wearing Joseph's sweater on the yacht. So... it kind of implies they had more than a one-night stand IMO despite what Joseph says.
I think Robert and Mary were friends beforehand, and this is a big reason why Robert's so pissed off. He's not just mad at Joseph for failing to commit to him, he's mad at himself for fucking a married guy.
>>3122036I doubt Robert "was under the impression the marriage was over", he probably just thought he could win Joseph over because Joseph is clearly unhappy in his marriage.
What I really don't get is all the Robert love vs Joseph hate when Robert has done plenty of shitty things not just relating to Joseph's infidelity. They are alarmingly similarly shitty, but for different reasons. Yet Robert is just a poor precious baby who needs love while Joseph is the worst person ever. I feel people just feel annoyed Joseph stayed with his wife instead of choosing them/the MC.
