Should i break up with her?

I have this girlfriend and I love her to death, she's my world. We've been going out since 6th grade and we're both 21 now. But she farted yesterday when we were having and I was like OMG EW and she left and won't talk to me. She's being a ***** about it. I didn't mean anything by it. Farting IS gross, right? Couldn't she have held it in until we were done, Jesus.
