Ok, then, I agree - if she wants comfort from you while she walks out the door - that is unfair to you - stand up to her. Withdraw the comfort. If she thinks she wants out, she has to see how that feels and that means not still being dependant on you to comfort her while she decides to leave. It's tough. It's a bit of emotional manipulation she's pulling on you.
Would you feel comfortable saying "Yeah, this is sad" and walking away when she wants to cozy up to you?
PS Counselling is good. No matter why she tells herself she's going in there, it's good to get in there. You have no idea what can happen in there.
