<human>: My boyfriend and I went to a party about 7ish months ago and we met some new people. Since then, he has been consistently (at least once every couple days) lurking this one girl we met's Facebook page as well as a couple other girls, both of which he used to know. 

I want to add that yes, I invaded his privacy by looking at his Facebook search history. I realize this calls our trust into question but to be fair, we have access to each other's Facebooks so I didn't go on with the intent to snoop. 

I want to know if this is something I should be concerned about regardless of the fact that he says it's out of "curiosity". He met this girl once and it implies he thinks about this person very often enough to take the time to search and lurk her on Facebook. It made me feel sick because in my mind, it says he is interested in other people and I thought things between us were going great. 

In all honesty, I lurk Facebook from time to time, everyone does. I have lurked someone I've met at a party before, however it's usually a one-time deal. The fact that he has been repeatedly doing this with about 3 specific women on an almost-daily basis concerns me and I am thinking about ending it because I feel like he is a creep.

Can you condense the text into a few key points?
