Open Question: Did they delete their fb?

I think my bf delteted his fb because on my relationship it says "in a relationship" but no longer has his name..he wrote something on my profile before so i clicked on his name and i can still view his profile and on his relationship status it still has my name tagged, on his recent activity (from yesterday) he commented on a picture so i clicked on it and it shows the comment on the picture but it doesn't say he posted the comment or show his picture? has he deleted/deactivated his account?
