the daughter

I'm in season 2 and I'm really disliking her:


First, she's sleeping with her father's rival.

Second, she told this same rival about her father's drinking problems thus his job.

Third, she tells him the secret about the Mother's death thus compromising her father and Henry's freedom.

And she's angry he keeps secrets from her? She reminds me of Sansa somewhat spilling the secret to the enemy. If she sleeps with 10 men, will she detail her entire family's secrets to all of them? She's not to be trusted because she spills everything at the first opportunity.
