<human>: My girlfriend and I just had a conversation about how she said if she found someone better than me, she would immediately break up with me and date him. I personally feel like that's a pretty terrible reason to break up with someone, and I told her that if I found someone better I wouldn't break up with her, because I value our relationship and all we've been through together.

She then went on to tell me that she would be totally fine if I broke up with her for that reason, to which I responded that I think she would be angry. She said that I should try it and see. I told her that I didn't think testing something like that was a reason to break up with someone either. Of course, she disagreed.

I'm quite frustrated with this whole conversation, and I would really appreciate any second opinions or advice on what I should do. If you need any additional info, let me know.

Can you condense the text into three sentences or less?
<bot>: Girlfriend thinks that breaking up with someone for someone else is a good reason to break up with someone, and that breaking up with someone to see if they would be mad is also acceptable.
