Piglet, the poor guy knew the op was intending to buy herself an iPad with the bonus money before Christmas and was fine with it. The fact she didn't get round to it, and is now sulking because he is buying her one (and not the one she wanted) hardly means he doesn't love her or care for her. Sure, it might be a gift of convenience, but it isn't as if he's bought her a new iron especially for her to use on his work shirts.
He's probably entirely baffled. If she was that desperate for an iPad, she could have bought it herself four months ago with his blessing.
Far too often women leave themselves last in the treat stakes and convince themselves they don't deserve it, or oughtn't to bother, or feel guilty about treating themselves, and put their husbands or kids first.
'Before Christmas I said I was going to get myself a tablet but never did bother'
How that translates to 'he doesn't care for you or love you' I can't imagine.
It's rather more the op not caring about herself enough and putting herself last.
Only on mn could a dh buying a tablet for his wife's birthday end in discussions of financial inequality and suggestions that he doesn't care or even love her.
