Do I walk away from WAW? (3)

[1foot2]

Well, I texted her to ask how she was feeling yesterday afternoon and she responded that she was still sick but "trying to come home". Later that night after kids were in bed I texted again, asking when she would be home, as I had plans to meet up with some people. Her response was "really? I'm still really sick. Can you cancel?" Ok then.

Hasnt come home yet today, so she's been gone for 36 hours. Starting to think the pregnancy is involved with this somehow but there's no way of knowing.
