<human>: Give me a shortened version of the text

We've always had a very happy relationship but now it's come out that she has believed all along that I am in love with another girl. She once had a dream that I cheated on her with this girl and woke up crying about it.

The girl in question is a girl I liked for about 2 months nearly 2 years prior to meeting my current girlfriend and I have no history with her. She is just a friend in our circle.

Basically, despite my efforts, I cannot convince her that these claims are complete horse-shit and she has decided that we go on break until after the weekend (at which point I fear that her paranoia will result in her breaking me off). This all triggered last night when I walked home with said friend after my girlfriend decided to stay out late.

Can I convince her otherwise? Should I be the one to cut it off? Please help, I would do a lot to prevent this relationship from ending.
<bot>: Girlfriend believes I am in love with another girl. I am simply not. Girlfriend has reached the point of wanting to end our relationship because of it.
