Rose,
When I focus on you and the situation, I sense that your newly married co-worker is trying to adjust to her new home life. I have a feeling that her new husband might be a bit controlling. It appears that she is transferring her frustrations to others when she reports to work.
For now, I would suggest that you distance yourself from her on a personal level. You need to continue to work with her on a professional level. Just be yourself, courteous and polite. You might want to refrain from discussing anything of a personal nature. In time I think she will come around. She will miss and need your friendship. This might take awhile though until she realizes what she has been doing.
You are a very caring person and I am certain that you have many friends.
