In all seriousness though, I wouldn't stress too much about it becuase she may just need that little bit of time to sort things out. I would imagine that once things calm down, she'll return to you (hopefully) and things will be better than they were before. "You don't know what you have until you lose it" kind of thing... although I know she didn't 'lose' you, but she is going without you and it will help her to realize what she had. Especially with a child on the way, my wife is prego too and man, she's up and down, left and right all over the board with emotions sometimes. So you have to let them play these things out. I would bank on her eventually coming back to terms with life and the way things are going and returning home and putting that ring back on.
Humans are the only creatures that won't live up to the their potential. Give everything your all. When you die, die on E.
So I ask you, what do you intend to do now?
