<human>: Can you give me the gist of the text in a nutshell?

So when I was starting to get interested in seeing this girl she said she was stopping smoking and would quit and I wouldn't have to worry about it. I am not alergic to it I don't think but I have a very sensitive nose and the smell of that on clothes or on her breathe is very nausating to me. 

We have been together for a little be longest than 6 months and besdies the smoking I really love her. She broke down crying to me a few months ago saying she was lying to me when I would ask her if she just smoked becasue I can almost always smell it on her breath or on her clothes. She would fake get mad at me when I asked and deny it which would make me feel horrible about asking her and being wrong (or so I thought). 

Now she did it again and this time she says "whatever" and "I told you I can't do it". I offer her help like buy her the patches or gum or anything else. I have not got super angry about her having a hard time quitting but I have got mad about her lying to me about it.

Reddit, what should I do? I really, REALLY like her and want to stay with her but I can't take the smoking at all.
<bot>: My GF has all but given up trying to quit 6 months into our relationship. Now I'm hooked on her but disgusted by the smoking.
