And Gale is another lying jerk who is all jovial and nice and friendly, but actually he's a nuclear time bomb on legs and at any time he could wipe you out.
I've seen a lot of gale hate variously, and never understood it, not really... I don't want to imply that it all stems from petty resentment over the idea that he asks you to give up a couple of magic items due to his condition... So...
First question, I guess.... What did Gale lie to you about? The idea that he's a terrible lying nasty seems to be quite frequent... so... what is it that he lies about?
I think he only actually lie if Tav romances him, no? about the whole bomb and his ex that he only tells after he slept with Tav. If not in romance I don't see lies, he just says that he won't tell you and demands blind trust. I say demands because he is adamant and if you refuse (which let's be honest makes sense in this case) he will go after other ways to get what he needs.
