I'm afraid that your post Illtellhim has been a bit of a thread killer. While the sentiment is admirable, and most of us would agree wholeheartedly (as I do though I am not at all religious) it presupposes that only one person in the partnership is in need of 'care' at a time. This thread has been about 'who cares for the carer' - given that this is a Grandparent's site, it is reasonable to suppose that most of the contributors are older folk who are likely to have some health problems of their own. Who is to look after them if their life partner is not able to through illness or disability?
Also, not all marriages/long term partnerships have been happy and fulfilling, with mutual support and give and take. Marriage vows may have been broken or the couple may have stayed together for convenience or the children's sake, with no love between them. Yet the partner left standing is expected/forced to undertake the caring role. I am not in that position but I know several women who are, Even I am now caring for a much loved husband who is changing into a stranger, without shared memories, who keeps asking 'when am I going home' - he means to his childhood home, although we have lived in this house for 45 years and he renovated it extensively and built the extension with his own hands.
To end on a positive note, the NP at the Day Therapy Unit has arranged for DH to continue attending on Wednesdays for another 6 weeks and has contacted the Day Care providers, urging them to 'fast track' DH's referral. Hooray.
