My boyfriend has made mistakes in the past regarding drugs. It was before we met and so it doesnt really bother me too much. The past is the past etc. However, a week or two a go I found a meth pipe... which he explained away and I choose to give him the benefit of the doubt and to trust what he was saying. Then this morning I've found a cut straw with one end sealed... used for snorting. I'm obviously going to bring this up with him but I dont really know how to go about it. I dont want it to cause a massive fight, which is usually the way it goes, but I dont want to go too easy either because to me its pretty serious stuff and I dont want him feeding me more bullshit.

Any help or advice would be very much appreciated. Thanks
