I understand fully the point you are trying to put across, as I am in a very similar situation.
I have always been the force and the mind driving my family and my husband has been happy to go along with all my decisions.
Now, though, I fear for the future, as my husband does not really understand what lies ahead for me and the fact that he might have to become my carer.
He is showing hardly any empathy for my predicament and thinks I'll be able to carry on in this way for the foreseeable future. I am thankfully still able to shop, cook, wash etc, but how much longer can I continue to do these things?
I think that wives ( I am not trying to be sexist, here, but I am just reflecting on facts) make better carers and have a better understanding of the difficulties facing Parkinson's patients. Look at how wonderful Goldengirl is, for example. She comes on this Forum and keeps herself well informed on the subject. Her husband is so lucky to have her as his carer!
However, Maya, I don't know for how long you have been married, but it is surely your right to expect your husband to support you in your hour of need simply because of what you have done for him until now.It is surely his duty to take care of you.
Keep smiling, as that is all we can do in the face of this horrible disease ! I wish it would go away!
