@Lindsey1988,
Stop looking.
Beyond that, people change their privacy settings all the time. It doesn't necessarily mean squat.
Now go outside and take a walk or visit a soup kitchen or call a friend or pet a dog or pick a flower or take a class or whatever it takes to get you off Facebook and to stop looking at stuff that stopped being your business when your earlier relationship ended.
PS If you think that's not a nice comment, you should see me when I'm not being nice.
