I was recently talking to my mom about maybe contacting my ex from over a year ago (probably not a good idea though Anyway, she told me that apparently my aunt and uncle dated back in highschool, then broke up when they went to college. A few years later - don't know the specifics - they got back together and have been married for many years. I didn't actually know I had a family reconciliation story but I do!
Oh, not sure if this counts but my brothers girlfriend of almost 8 years now broke up with him last year, they are highschool sweethearts. The breakup lasted about 2-3 weeks (I think they emailed back and forth and talked on the phone) and then they got back together. It's a weird situation though, they constantly argued, she wasn't sure she wanted to marry him and literally wrote him out a list of demands - things he had to change for her to take him back...most were absolutely ridiculous. Not sure if it's a happy ending yet, he was destroyed at the time and I almost wish they didn't get back together so he can find someone less high maintenance
