Search Results: should i dump them

Disclaimer: We did not break up because of her obsession. lol

But is it normal for 21 year old women to be obsessed with pooping? I've really been curious about this.

About a week into the relationship text me that she was cooking her favorite dish and it gives her enough farts to fill up a gas tank. I told her that was nasty and she said she was sorry, but it was true. Then she goes on to tell me her most embarrassing poop story about how she sharted at Burger King and almost didn't make it to the toilet. I really thought maybe this is just a getting to know each other phase where we share embarrassing stories, but no, it escalates from here.

One weekend, she's on vacation with her family and is in a hotel room with her siblings. I wake up one morning to a text from her asking for advice. I say sure. Then she tells me how she has to take a dump, but doesn't want to wake up her siblings by moving around too much. She was asking me if she should hold it or just go. I told her to just go, but she changes her mind because it's not as bad as when she has FBS (her made up family bowel syndrome where someone in the family randomly has to take a huge crap that they can't hold in).

Another time she sends me a picture herself pooping in a stall-less public bathroom. She complained about how there's no privacy. Then she tells me about how she got revenge on her RA for giving her a citation when she stayed in her college dorm. She broke into the RA's room while she was gone and took a crap in her toilet and didn't flush it. The RA came back and saw the poop, sent an angry email to the whole floor, and got her supervisor involved. My ex loved this and called it the best revenge prank of all time.

Is she mentally stable? Are there other girls this poop obsessed? Why was she like this?

I posted this question earlier but forgot to add details.

She finally admitted it to me. My brother started to flirt with my girlfriend and kissed her. She then slept with him in his bed. She cheated for 4 months, and then dumped me for him. Since I live at home , I see her often, but she sleeps with him. What the fuck do I do? Its been going on every other day for four months. Need to vent and get over this.
I got so angry at my brother I started hitting him everywhere I could and now I try to avoid him.

I guess my parents were trying to protect him from his actions
That's my guess.. I never received a response to that question from them yet ADVICE PLEASE?
