Iam64 What you are speaking of is not what I would describe as being emotionally dependent. To me emotionaal dependence means totally being unable to function without that person.
A very dear friend died last year, Her husband, a lovely man, was emotionally completely dependent on her. Before her sudden death, he was showing some signs of memory loss. In the 6 weeks between her death and funeral, he had a complete collapse. A few days after her death I visited him and he was entirely rational and functioning. At her funeral, he clearly had no idea who I was and a few weeks later went into care. I have visited since and he has no memory of anything of his past life. Even his son, who visits regularly does not think his father really knows who he is. His father is not yet 75.
This is what I mean by emotional dependance. I would not say anything that would suggest a diminution in the sense of loss and grief at the loss of someone very dear, but that in my mind is not emotional dependence. Of course you miss someone close, but you can still get yourself up in the morning, look after your home and yourself, get about outside, unless you have physical problems,
Over my life I have seen several cases where, when one spouse goes the other completely collapses, in much the manner described above.
