Is NOBODY wrong in the post ? POST : Throwaway because she knows my main.

My (now ex) and I have enjoyed a pretty wonderful relationship for about 8 months, and all seemed to be well until about a month ago, when she accidentally farted for the first time in front of me.

She was very embarrased but I tried to make her feel better by laughing it off, but over time it's become increasingly frequent to the point where she farts multiple times an hour. I guess she thought it was ok after I laughed it off the first time, so it was alright to keep doing it? When I pointed it out to her, she asked me why I thought she farts so much, and I responded that it probably has something to do with her diet. She only eats cold cuts, guac by the spoonful, McDonald's, and pizza rolls. She then laughed it off but refused to change her diet, but resumed asking me the same questions later.

This morning I got fed up, and told her I just needed some time for myself, but honestly, I just couldn't handle all of the farting.

She won't stop texting me and I had to block her calls on my phone. I feel bad but it's just too much.

Am I the asshole here?

Tl;dr: my gf farted, I laughed it off and she took it as a green light to do so multiple times an hour, which prompted me to leave
