CONFLICTED & CONFUSED

I have been married almost five years and for most of that time my wife has suffered with depression. She didn't admit that she had been diagnosed with depression until after we were married. Soon after we got married she was hit with an onslaught of physical ailments from fibromyalgia to uterine fibroids.

I have encouraged her to seek professional help for the depression from the beginning to no avail. We have a 3 year old daughter and she is unable to physically or emotionally care for. Throughout the years she has threatened suicide, but never attempted it. I covered up her depression, made excuses and ignored signs. Recently, I told her I was moving an hours drive away and I believed my daughter should come with me. I work nights and have become afraid for my child's safety since her mother can't physically care for her. Am I wrong for doing what I feel is best for my child's and my best interest?
