I just think all the romances are forced and unbelievable.
You just crash to Faerun on a mind flayer vessel. You meet these people and spend a few days with them. You do a few things they like and BAM. "Sleep with me."
Lae'zel is Gith, and though I don't think she's what she pretends to be, I would think that she would be WAY harder to romance than, "You killed gobbo leaders. Let's do it."
I think for Lae'zel it's not really romance. Your fate is unknown at this point and you might turn into a mind flayer any day,. At least to me her offer (and Astarion's) seemed more like "let's party now, because tomorrow we may die", so for them it is in character imo. I doubt the githyanki society is big on romance anyway.
It's certainly not romance. It's 115% carnal. And the abruptness of it isn't because of the impending doom of turning. It's cuz she got hot and bothered by all the (assumed) fighting and killing the party does when taking care of the Goblin quest. Both Lae and Astarion are hedonistic and self-interested, so them being wanton at the party made sense to me - especially making a pass at Tav because
conquering the leader feeds their egos.
First playthough: I used gale in my party a sum total of twice and my interactions with him were bloody limited. Despite this fact, he somehow ended up as having a pretty darned high approval rating. I think I spoke with him maybe less than ten times counting the two times I told him to get back to camp. Don't get me wrong I have nothing against the single most run of the mill generic wizard ever to wizard but, he didn't make the A-team
and so he ended up on the bench with shadowheart who I also had very few interactions with and seem to irritate just by existing....
Once you recruit companions, you will gain approval and disapproval regardless of whether they are in your active party or just sitting at camp. So for all you do-gooders out there, Gale and Wyll will always have the hots for you if you recruit them. I'm of the camp that this is intentional due to the tadpole connection, since several hotfixes and patches have gone by and it's never been patched out. Though there is still the bug of companions approving even when dead... so who knows.
