Do you think YLS ever had "romantic" feelings for LHC? What changed between them?

Do you guys think YLS ever truly had "romantic" feelings for LHC? Did she ever see him as boyfriend material, or did she always just see him as a big brother type figure?

From these passages, it appears that she did have romantic feelings for him at one point-

岳灵珊低声道：“但如是我死了，你便不想活了？”令狐冲道：“正是...” 岳灵珊紧紧握住他的双手，心中柔情无限，低低叫了声“大师哥”。令狐冲想张臂将她搂入怀中，却是不敢。两人 四目交投，你望着我，我望着你，一动也不动，大雪继续飘下，逐渐，逐渐，似乎将两人堆成了两个 雪人。

and..

令狐冲微笑道：“.....好妹子，你下崖去吧。”岳灵珊目光中含情脉脉，双颊晕红，低声道：“你叫我甚么 ？”令狐冲颇感不好意思道：“我冲口而出，小师妹，你别见怪." 岳灵珊道: 我怎会见怪？我喜欢你这样叫."


Yet, from her conversation with Ling PinZhi in that carriage, YLS claims that she always only saw LHC as a big brother, never as a boyfriend, and only had romantic feelings for LPZ.........

岳灵珊道：“平弟，你到此刻，还是不明白我的心。大师哥和我从小一块儿长大，在我心中，他便是我的亲哥哥一般。我对他敬重亲爱，只当他是兄长，从来没当他是情郎。自从你来到华山之后，我跟你说不出的投缘，只觉一刻不见，心中也是抛不开，放不下，我对你的心意，永永远远 也不会变.........”

Finally, what do you guys think was the reason LHC and YLS's relationship fell apart? Was it because he got jealous over LPZ, and flicked her sword into the valley? Or was it because she thinks he tried to stop her from teaching LPZ? It seems ever since then, she has been rather cold/vicious towards him.

岳灵珊脸上一红，道：“我便是恼你，我便是恼你！你心中尽打坏主意，以为我不教林师弟练剑，便能每天来陪你 了。哼，我永远永远不睬你......"

Or did she just find LPZ to be more attractive?
