My wife has had problems with depression for years. The past two years she has had really bad emotional issues, especially when she was pregnant with our last child. These problems were pushed off as she needed to be strong and she would get over it. I started working out of town and now everything is falling apart. I need to know why she now says she is through with the relationship because I don't know what went wrong. I don't see how it is grounds for a divorce. any insight would be great.
