My ex and I have been broken up for quite a while (over a year) and haven't remained close; however, we bumped into each other recently and had a very amicable chat, during which I felt a lot of chemistry still lingering.
So strictly as a mental exercise I'm considering whether it's possible to slowly re-establish communication with her over time until I finally pitch to her the idea of getting together again.
My roommate (a female, I'm male) says I'm nuts and that if we broke up once, it wouldn't work a second time. I disagree, but I'm of a devious lot.
