I am so so obsessed with Gale's romance because God it's so clear he worships your Tav through it and it's absolutely horrifying.
His love through so much of the game is in *spite* of himself. Is in abject hatred of himself. He is holding guilt and shame and self loathing so bad he'd rather unmake himself into something that the Tav never loved in the name of some notion of "deserving" because Gale is *so* broken by Mystra even still that he thinks he must earn Tav's love. That he must make himself *worthy* of all that Tav has to offer.
Do you know how horrifying that is? To realise the person you love would destroy themselves for you, in some desperate attempt to please you, and with it take away everything you loved about them and they ask you to be happy with it?
Gale lays at Tav's feet a love that is built on worship, on looking at the Tav as divine. And it's not until the VERY end and you being really patient and stubborn does he begin to see Tav as a person. And that's horrific. He loves you so much he'd destroy himself.
He has placed you in the same spot as Mystra, but you are no all powerful Goddess, you do not spin magic along with a wave of your hand and seeking to mould him. You are a person. A person who is flawed and human (in the personhood sense of the word). A person who he does not have to prove himself for. Unmake himself for. At that point, he doesn't love Tav, he loves the idea he's made of Tav. And this idea, it's been built at his own expense. He's hurting, he blames himself, so even in the love that requires no proving oneself, no supplication, no means to *earn* it he takes it upon himself to make himself "deserving" and maybe he'll finally be content with himself if he just gets enough power, makes himself better, makes himself someone who is not him.
Because he hates himself.
And that is so heartbreaking to watch, because it's so very clear he has had zero time to heal. You are in love with a deeply suicidal depressed man, who would rather watch himself burn than accept your love for him as it is. Whole and human, with no notion of "deserving". The foundations of the love he has for Tav are so so unhealthy. And I love it. I love him. I want him to get better. It's so sad we don't get to see more Gale Dekarios in the game. He's so interesting in comparison to "Gale of Waterdeep" and I'm glad he has a chance to go back to it.
