Smoking marijuana isnt the worst thing for her. I know that it can be very easy to become dependent on it. However, I know that it isnt the worst thing you could do. I cant help with the anxiety that people face everyday. I don't mean to blow it off, but it really shouldnt be such a deal breaker for you. If you truly love her, you would accept that, no matter how hard it may be. I understand being a parent and not wanting your children to smoke. If you really want this to work you have to sit down and tell her how you feel, but that you do love her, but you dont want her doing this around your children. It can be extremely difficult but sometimes if you love someone you have to let their bad habits go. It sounds like you are crazy over her, dont let this ruin it for you.
