DH has worked since the age of 15 and is 65 next month, so it is literally a matter of hard graft on his behalf - my own contribution is tiny compared to his.
I am so proud of him. His parents were basically subsistence farmers. DH was denied many opportunities on the grounds that he was the only boy and thus expected to take over the farm.
I'm actually crying writing this as it's so momentous.
It can be done. Hang on in there!
