Like Barry Cooper says, for every person who knows about your grow, your chance of getting busted goes up 10%. He tells one other person, now you're at 20%. Unless you wanna make a few bucks, don't smoke your stuff with him. Like you said, he'd know something was up. We all got bills!! your car needed a new alternator, tie rods, some unexpected shit came up, etc. Reduce your order by half each month or two. That way HE begins to move on. Furthermore, lead on how you shouldn't be even spending that, considering your financial troubles. He knows you haven't QUIT, but its perfectly acceptable to let him know you have to cut back. Later on, gradually keep cutting back some more.. Soon enough he wont even notice when he hasn't heard from you.
