I think we all are entitled to our own opinion.Tara's lying to Jax is not really new.I mean even last season she lied to him.I know why she is lying or whatever but lying is still lying,No matter how.Manipulative behavior is next to lying.When you lie to someone,you are manipulating that person.Don't you think so?But still it's just my opinion base on what I have seen so far in season 5.That Tara has changed for worse and I don't really see the reason behind it.JMO
