I can't be sure either, "cupola" means many things.
But I think too much, so here's my take on it.
He's in love with a woman he can't trust, and she can't trust him. Of course it's sexual, all romance is sexual. He's going insane, she's going insane. They need to be close and can't bear it at the same time.
Maybe cupola is some.. sexual reference, because it can be... sort of like a penis or like a breast in appearance, but it can also mean a place built for observation. So... It could just means he sees everything, he sees his mistakes and can't stop himself.
He pushes her to see if she'll push back. This song is about that agony of waiting to see if the other will keep pushing, seeing if the other needs them too. Inability to believe the reality that he can be loved by her.
