<human>: Can you condense the text into a few key points?

I have been in a long distance relationship (LDR) with my girlfriend for 5 months now. We had been best friends for nearly 2 years before that. She lives half way across the United States from me.

She dated a guy for about a year, she was single for a handful of months, and then I went over and met her in person for the first time and we began a relationship. I get to see her once every month or two for about a week at a time.

She has been kind of having what I refer to as a pre-life crisis. She is freaking out about not knowing what to do with her life among other things. She has been a wee bit emotionally unpredictable. We have always been very open with each other... but last night she said something that upset me. She said "I regret breaking up with my ex-boyfriend".

How am I supposed to feel about this? I feel like that is the equivalent of saying 'You are the second best. If I had the option of returning to him I sure as hell would.'
<bot>: LDR girlfriend says she regrets breaking up with her boyfriend. I am hurt and feel like a back-up plan.
