I know that it is supposed to be people I interact with a lot. Mostly it is family, people I have a lot of mutual friends with and a lot of interaction with. But I'm just curious because I was dating someone for about 2 months and we stopped seeing each other about 3 months ago. We have zero photos together, have never written on each other's timelines, only one mutual friend, I have not viewed his page in a month and have him blocked from my news feed because I do not want to see his posts. What may cause him to be in my top 6 friends about 1/4 of the time I look at my own profile?
