Actually Nero, I am pleased, though not surprised to learn that it isn't money. I didn't think it was, and it isn't pathetic to remain where you are because of love and a long long relationship. Life is full of compromises, and like I said, I didn't get to make the choice that you did. I actually talked about it at bomb drop but my xh wanted OUT (yeah right, still around nearly nine years later, but there we are!).
I like URworthy's advice too - you are doing the things that your partner needs. Love is a funny thing and it isn't all about our ego and what we want and what suits us. I think that is why love can be so easily abused - because it is kind and suffers long, as St Paul says.
I suspect that if I were in your shoes I would be much as you are. Staying with the situation because of what there was. Half a loaf is better than no bread, especially when you are over 60!! Is that a 'good' way to live Idk, I really don't. Some folks here seem so sure about everything, but the heart is a strange thing.
Btw I also wondered about a brain tumour! But he had a full MRI scan in connection with another health problem, and apparently not.
