<human>: Can you provide a brief rundown of the text in within 3 sentences?

1.Okay, so me and a long distance friend of mine, let's call her Polly have a weird arrangement. 
   Our personalities are such that we are almost identical. That can be good or bad. 

2.We randomly met up for the first time when she was on a business trip, her idea, and clicked pretty well. Long story short, we kept texting and texting, and somehow through a bit of weird chemistry (again weird because it's a bit insane how close our past relationships have been, how we both handled them, and how similar we our) we ended up with this pact of, if in 18 months we're both still single we're gonna try and date. It was her idea, unprompted. Basically, no strings attached if we're both still single on February 1 of 2018, we meet up for a weekend and then see what happens.*

3.We're both into the idea of a good story, and I've been dating around - there are lots of single girls in Nashville. The distance is the primary reason we're not trying anything right now. I'm in Nashville, she's in Reno, and not in a place in our  careers to up and move for a potential fling.*

4.It's intriguing to me, that's for sure. I like the idea. But I wanted an unbiased set of eyes to tell me if this is crazy. Because it's not strings attached, and we'll both keep dating during that time period.
<bot>: Have a pact that if in 1.5 years we're both still single, we give it a go. Is this weird and a red flag, or just hopelessly romantic?
