How do i get my girlfriend to stop farting?

She blasts off about 40-50+ a day and they always..always stAnk like hell. The worse part is she thinks its funny and cute. YEAH CUTE. seriously its nasty how she does it and she doesnt even have to eat anything. and i know she can hold em cause when were around people she holds em, but then the millisecond were alone she'll rip about 1-10 and stain my car seat green. So unattractive and I have told her this and she still does it and laughs, even farts on me sometimes and says arent I cute? HELL NO!! Breaking up isnt the answer I need a real cure. I have no idea what i should do, help please, I need to put a cork on my smelly stinkbomb of a girlfriend. Cause any attraction I have is stinkily flying out the window fast.
