dude, stand your ground. if you had nothing else to offer except giving up weed, then I could see it. You can be gentleman, treat her like queen, but still toke. It starts with weed (which happens to be something you like)...it's an easy card to play because of the legal issue, but then where does it go? You're letting her tell you what to think and how to act...You seem young, and you're probably loving the sex...no vagina is worth giving up the person you want to be. Others women will do things you can't believe your girlfriend might be doing for you.

And don't cave into that "if you love me, you'd quit" seemingly respectful but actually passive aggressive crap. You're weakening yourself, and it has nothing to do with her.
