Yen: why so unfriendly?

For those who, like me, have only played The Witcher 3 and haven't read the books (yet... still on my to-do list), I can completely understand why they prefer the romance with Triss. And I am only hoping that I can change my mind when I read the books...but I don't know...

Triss is affectionate and head over heels for Geralt from the start, whereas Yen generally treats him pretty poorly. When she kisses him or they have sex, it feels like she's rewarding him for behaving well. He's supposed to be her partner, not her lapdog!!!

He's a tough guy in general, but with her, he acts like a complete pushover...

Also, Gerald's friends and "family" (Vesemir and the other witchers) like Triss over Yen because she treats everybody like shit, basically like they're her slaves, with a huge air of superiority. Not even the excuse of looking for Ciri justifies that mistreatment...

Damn, forget about Triss for a minute, just think about Yen: those justifying her behavior (she's more mature, she knows what's best, they have a complicated history...) should think a little bit about it... would you like to be treated like this? Risking your life trying to find her after a long time, over and over again, and when you finally reunite not even a hug? Just this cold, motionless face...

I have to admit I had so much fun when I found out she threw the bed where Gerald and Triss had sex, over the balcony.

Despite all of the above, I did the canon choices on my first playthrough and I am romancing Yen (I guess this is why I am pissed now lol), but unless this changes later on in game...I know I won't repeat for the second playthrough...
