Have you explained to the neighbors about the 'can be randomly tested at any time' bit? I mean, if they're so nice why are they constantly offering what they would KNOW is a terrible temptation that might get get you arrested? I'd go to them first and explain it, just like you did here, and see if maybe they'll respect the fact that you're doing your best to stay clean.

As to your boyfriend, I really commend him for his attitude, even if temptation is getting to him. Let it be his choice and you'll never go wrong, but tell him that you appreciate his thoughtfulness. And keep hanging in there, you're doing great :)
