[act 3 spoilers] Astarion break up trigger

[Фулгрим]

I talked to zethino at the Circus and chose Astarion. My approval point's are high, but after that I talked to Astarion and said I'd like to repeat the night after saving druid grove. He said I didn't fullfill his wishes or something like that, but the only thing I remember is that he asked me to give him a tadpole later, and he has like 3 of them now. He wasn't in the squad when I met Raphael so he couldn't ask him about scars on his back, but I'm actually against him to make a deal with devil regarding reading some old poems. So what should I do if I want to keep relationship with him?
