What is defense against wife just up and leaving house?

my wife had friends come to house and moved all her possesions out. I had no prior notice. Basic problem is that she was caught in lie re: IRS: she was supposted to be paying for ~ 7 years of taxes she had not filed. I had just asked her if all ok she had told me yes. She is being manipulated by friend who has many personal problems. We sent Linda to Nurses school and saceificed much $ then she did not take the test for certification, her reason for going was because she said she would make $40,000.00 per year.
