Problems with girlfriend?

I'm starting to think my girlfriend and I are taking the seriousness of our relationship on different wavelengths. I'll be frank about this.. my girlfriend seems to be a little too comfortable regarding farting. She farts in the car, when we're showering together and in the bed. They're really hot and smelly like gone off Indian food. The other day we were performing a 69 and she let one rip in my mouth. The taste was so obnoxious I started dry heaving and thought I was going to p out. I also think I might have gotten pink eye from it. It's just getting to that stage where it's getting so out of hand I'm thinking about calling an end to the relationship but It's just I like her so much I don't know what to do. I need your help, thanks.
