You threaten to leave if she´s not truthful with you

You realize that this is as perfect of a chance to get some answers from her and/or leave.

You look her sternly in the face and say:

"Why me?"

Jane looks a little surprised for a second, then realizes what you are asking her about, she tries to hold her mouth then blurts out:

"I don´t want to tell you!"

You start walking towards the bedroom door and say:

"If you don´t tell me, I´m leaving!"

"I´m afraid to tell you!" Jane says.

You stare at her for a second, she looks so conflicted and frankly a little scared, a petty part of you is a little glad, now you have a little power in this relationship, as she can´t lie to you, but you realize that she´s answering in a way as to not address your question.

You say to her:

"Fine, If you´re giving me the run around, I´m leaving!"

You walk towards the bedroom door and right before you step through it you hear Jane yell out.
