I kind of got the feeling that even though she was lovey dovey at the beginning, that she wanted rid of him...

I had that same feeling, too. Now, I'm wondering -- did she really want to stop him from going in the first place? Or was that all just an act?

I mean, for someone who was extremely supportive and encouraging in the beginning (i.e., insisting that Rumple was definitely no coward), it seemed odd to me that she had no problem easily believing the rumor about his cowardly move. Not even giving the benefit of the doubt or wanting to hear his side of the story first? Just straight-up anger on her part? Weird. Again, it seemed like a major change from the beginning, and it made Milah's character seem more fishy to me.
