my bf broke up with me but constantly checks my blog?

my boyfriend broke up with me, but he's constantly visiting my blog, like 20, 25 times a day and several times at night. i know it, because i have a code installed on it. also, he doesn't know i know. looks like he wants to control me even though we're not together, it can't just be curiosity. what do you think it would mean? have you experienced anything like this?
