Looks like he's flirting with another girl on Facebook - liking a bunch on her pics (no comments though). Says he doesn't remember how he knows her.

Men get online and will look at females pictures allday. There are many men dont just chat. They chat with the hope of hooking up with the female that they are chatting with. I know a lot of men who have girlfriend and who are married but still get online and flirt with different women. And eventually chatting leads to something more. Please dont ever believe that a man just sits and chat online with the hopes of getting nothing of it, especially if the females stays in his area. Now if she didn't stay in his area, then sure he will chat with her online but thats about it.0
