It should still work, I think. My Lena never stopped sleeping with Robert, and I got this to work. Crucial is just to have both Robert and Ian at the life drawing event (never did the music event, dunno if it works there too), and as Ian make choices that lead to a fight.so its not going to work for me . my lena still in relationship with robert . damn wish i could do that .
thanks fo help
(I also let Ian get beaten up and constantly tap out to avoid too much damage to the relationship with Lena)
