Do guys Facebook "stalk" after a breakup?

We both loved each other but he had some anger and jealousy issues and we kinda broke up (more of an argument where we walked away and never spoke again).

I always have my settings on friends only, but have been uploading/updating pics/status from my phone and just noticed that the settings were on public.

Would he have seen my updates? Do guys ever Facebook "stalk"?
