My partner suffers from mental health difficulties (exhibiting symptoms of post traumatic stress disorder and multiple personality disorder [now called dissociative identity disorder]) and physical health difficulties where they require the support of a wheelchair.
Unfortunately, despite repeatedly trying to get any diagnosis for the last three years my partner is without a diagnosis for any of these health problems as of yet, so I have to be there supporting them every step of the way.
Even though we are both unemployed, I have no issue supporting my partner with their difficulties with our joined Universal Credit income but recently I noticed within the banking app on my phone there is a new option for life insurance.
I'd just like to put a disclaimer here, I have no intention of killing off my partner. 
So I looked into the life insurance just to get a bit of an understanding and this is what I found.
- Guaranteed 60+ Life Insurance = No good to me, I'm not 60+.
- Life Insurance = Pays out if I die or am diagnosed as terminally ill.
- Life Insurance + Cancer, Heart Attack & Stroke = Pays out same as life insurance, but includes if I am diagnosed with cancer, a heart attack or a stroke, even if I recover.
Naturally my brain goes towards option 3, it seems like a better option if I were to get life insurance at all as that'd still allow me 3/4 chances to continue to support my partner.
Having said that, am I being unreasonable to think that it might be pointless to get life insurance on myself when my partner would be unable to look after herself if I died or unable to support me if I needed her to?
