Not terribly long ago I found myself on a dating site after a 5 year relationship. One of the first people to come up was my ex. With a compatibility rating in the high 90s. After blocking her I went on a series of dates with other ladies that the site had assessed a high rating, and every one of those dates was merely meh. Then a lady came along with a compatibility rating in the low 80s and we hit it off immediately and are now engaged!
