Sunny, Whatever you do, do not leave your home. Once you leave, it is called abandonment and you do not want her to use this in court.
I'm glad everything has turned out well and you have electricity once again. Of course, she's going to appear normal around others because she needed them for food, warmth and electricity. Now that things have gone somewhat back to normal, she'll proceed w/the divorce.
Your family is a wonderful family and I don't know how they appeared normal around her after what she and her family pulled about the wedding. That just goes to show that your family has class and does rise above the circumstances.
Hang in there...again...do not leave your home. If she wants a divorce, she will have to pack her bags and leave...no more molly coddling her.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
