For someone so generous and financially fortunate, I'd be surprised if he wasn't paying for 99% of everything.
Shan't begrudge him that, it's his money that he's worked hard for it at what's becoming increasingly clear now to the detriment of his health, and he'd done the honourable and right thing and ensured his family and son were set up financially and with housing etc (I'm talking as a whole there, as of course he had the responsibility to ensure B was financially safe and safely housed during his childhood at least), so if he wants to treat his partner to regular high end clothes, who am I to judge?
Honestly the amount of conflicting stories and crap out there is just insane and bizarre, when most likely he was a normal lad thrust into not so normal circumstances, who then inevitably struggled with his mental health and resulting addictions, and whilst doing good works as a whole, probably did fail like a lot of us would and potentially do some not so nice things too.
