Wow, I’m so sorry to hear this, I just got back from a night shift and I’m absolutely shattered so I’ll come back tomorrow but the 70 grams in 6 weeks isn’t that unrealistic for someone to do. At my worst I would buy 3.5 a day which cost 200 say 5 times a week so that over 6 weeks would be 6k
If he’s buying it as single grams and paying top dollar of 100 per the its not too far fetched to rack up a bill like that especially if some of the money was used on other things like drink.
What I’d say though is for someone to be doing a large amount every day, there would be huge tell tale signs.
He wouldn’t of been sleeping and would look wrecked.
Not eating
He would of seemed massively “off” or weird to you
His nose would have taken a battering
He would have tried to avoid seeing you or spending time at home as much as possible.
I really do hope you’re okay and tomorrow I’ll come back and go over it all again.
There’s plenty of people on here who can support you and offer you guidance so I’m glad you found the forum
