My fiancee checked her ex's Facebook page. WTF!?

[Jojoman]

I saw on my computer that my fiance checked her ex-boyfriends Facebook page. Why would she have any interest in that? I did catch her emailing him about a year ago, so I wonder if she is really over him. I have keystroke recorder after that last incident. Is this just curiosity? Why is there any reason to do that especially since we just got engaged? Is this just a glance to her past or is this a sign that she is trying to contact him or longing for her past.
She didn't communicated, it, she just visited it. As they were involved and she had written him before, I am a bit puzzled. You better believe I am wondering about the wedding. Right now, I really have a big trust issues and it stems from this type of stuff happening before.
It wasn't a search for a bunch of friends, it was a search of other guys Facebook pages.
My question is, why is there a need to even care what they are doing? That only leads to a response from them and then as we all know, disaster follows.
She wants to be my wife, but still feels a desire to "see what they are up to." I have to call bullshit on that one!
I know it's not cool to record keys, but it started for her daughter and making sure she wasn't trying to sneak some information past us. Keeping kids safe is more important than their privacy. Molesters don't care about anything but their habit. I will protect this young girl with everything at my disposal. Kids lie. I know. I was a kid once.
We both are in our 40's. I think a little too old for games.
