To clarify further, my stance is not don't tell your girl, its don't tell anyone who doesn't absolutely need to know. If not, you are basically saying here is the option to hurt me bad in a legal sense, but I know you'll never do so b/c I know you. This is flawed thinking and can bite you in the ass. As far as knowing, yes an educated observant person can figure if their partner is using, but there is a big difference between basically knowing and implicitly knowing, particularly if they know where you store the gear. I understand the advantage of not sneaking around from a loved one, but realize that you are taking a risk b/c even the most solid relationships have the potentia to turn bad, and even in a moment of anger with the wrong information shared can lead to tragedy. Picture the scene cooling off a bit and now you, your girl and the cops are standing there with your stash. She realizes this is no joke and wishes to god things hadn't gone this far, but the pigs aren't leaving. This can really happen bros, and its not an indictment of women, its an indictment of the risk you taking revealing you use to anyone. It just so happens that most of us are heterosexual males and so the most common loved one we feel obligated to share with is our girl. She can know with out really really knowing, possibly saving her and you from doing something you'll both regret.
