I've just been replaying the game (with the new honor mode) and once again, the characters come across as way too needy and wanting to jump your bones way too quickly. There is little 'buildup - I should have to go looking for that, not just be nice to people. BG3 seems to equate 'being nice' to " I have feelings for you'. Maybe they should have hired a relationship advisor and not just someone for their sex scenes....
Example: after saving the grove, I made no overtures to Halsin, but the dialogue was offered to me to (without really knowing this character)to start asking very probing questions. I think that should unlock after a lot of travel and adventuring together. Its jarring. I was polite, said no - later there was a text option "I hope I didn't come across to strongly' or some such for my character - I had said *nothing* to encourage him. Then L'aezel - who I never said much too - has her whole 'you'll regret not sleeping with me' bit . It all sounds a bit adolescent. An Gale was gazing at my character lovingly because I was nice to him and my character likes magic so tried some out the magic he offered ...it wasn't a "I want to jump your bones' signal.
Is jarring enough that I can't think of any other part-based RPG where it was this blatant - and certainly not in baldur's gate or icewind dale etc. This playthrough I'm ignoring them as much as I can - but of course I need to keep them happy so there relationship stays good (or there can be in game consequences).
