Nah, makes no difference to me. She's known about you, and your parents, and the Templars and all of it since you were kids together and lied about all of it. By the time of her business trip (first time I played, before I, as a player knew about the Templars) I was convinced they were in a bad relationship and should break up. But it turns out that every minute you've known each other she's been lying to you about everything, dropping a few obscure hints that you can't possibly pick up on, isn't going to fix that for me. If it turned out she had been cheating on you the entire time as well (which is possible) she wouldn't actually go down any more on my list. She's already at the bottom. I believe that she's sad and has, at least some, regrets but she made her choices. She has no one else to blame and I would never trust her again.
