i don't think anyone should change for anyone but themselves... unless you want to stop, i don't feel you should have to. relationships are give and take true, but that doesn't mean they can take what they don't like away, and give 'freedoms' at their own disgression..

quitting smoking around her is enough... if she just looks at weed related stuff and wants to smoke, then she's fucked anyways. it's all over the place.. papers, blunts, bongs, pipes.... tv shows, movies, random people walking down the street... etc...

i think she doesn't want to admit to her own weakness and using you as a scapegoat so she doesn't feel so bad that she broke down and started up again.... i think she definately NEEDS to learn it's her responsibility to quit, and it's her fault if she breaks down....

i bet you she blames you for other shit that's her fault as well.... personally, if someoen can't take responsibility for themselves, i don't think they should be in a relationship...
