We’ve all had that relationship that broke off, but yet we wonder if the other person still has a secret urge to get down and dirty with us again. Or maybe fall madly, deeply truly in love the way they didn’t the first time around.

Either way, you’ve got these thoughts, right? And they’re keeping you up at night. No? Well, they’re making you read this hubpage, so I can at least assume I’m partially right.

The good news is that with the internet, it’s pretty easy to tell whether someone is over you. Let’s take a look at the usual suspects.

If you check your ex’s Facebook or Myspace page and the albums are still full of pictures of the two of you together, you can be sure that they’re probably not over you yet.

Especially if the pictures are those cutesy, squished-together, arm-in-the-air self portrait type pictures. Double especially if they are of you making out.

Actually, if it’s been at least a week and your ex tends to keep a pretty updated profile, you should just stop reading this now and call them if there are still hot makeout pics of the two of you on their Facebook or Myspace.

If they were even remotely on the market for someone else, those pictures would be history!

This doesn’t just go for Twitter, but any social networking site where the both of you hang.

If you’re constantly getting @’s on Twitter or replies or likes to your Facebook status by your ex, you can be sure they’re still into you.

One of my friends recently separated from her husband. He went from hardly ever using Facebook to religiously replying to every single status update, mobile upload, and retarded quiz that came up in her news feed. Every single one!

If he had paid this much attention to her when they were together, they might never have broken up.

For some reason, people stupidly assume that we don’t talk to other people.

You’re talking to your friends and all of them are saying things like: “Hey, John asked me how you were doing.” Or maybe, “Susie was bugging me today about who that girl was that she saw you with at the club last night.”

It’s a pretty big sign that your ex is more than just casually interested in your well being. They’re wanting to be a fly on your wall, or preferably a fly on your body. A wet, slippery fly.

Another case of desperate people being stupid.

Your ex knows that Wednesday is your Panera Bread day. You’re eating your Bacon Turkey Bravo sandwich and sipping your iced green tea when in she comes, trying desperately to look like she just showed up for lunch herself.

Problem is that she’s got that “I’m trying to look for someone without looking like I’m looking for someone” expression on her face, which really just makes her look like a twitchy schizophrenic.

And when she finds you, she gets to feign surprise. “Oh, YOU’RE here! I didn’t expect to see you! How are you doing? Do you have room at your table?”

Of course you have room, well, that is if you want her back. If not, you may want to put your feet up on that chair and be a bastard.

Here’s a biggie that may not apply to you.

Some of us get into relationship that get so serious that passwords are occasionally exchanged. It might be on purpose or it may be that one time you borrowed his laptop when your wireless card decided to fry and you really needed to check your email. Either way, the password is in the hands of your ex.

You log in to your Gmail and something is marked Read that you are pretty damn sure you didn’t read. Unless you blacked out at work, but that hasn’t happened since that day you and the girl in the next cube made Fuzzy Navels with the OJ from the cafeteria.

Then you realize that the only other person who could possibly have been in your account is your ex and you start panicking about whether he just read your Victoria’s Secret promo email or if he’s been reading all the stuff you said about him to your best friend right after you broke up.

But he’s interested, right? Is he still interested after what he’s read (or not read)? How do you knowwww?

There’s one foolproof way to decide if your ex really wants you back.

This one works except in cases where you can void foolproof systems by building a bigger fool. Assuming your ex isn’t said fool, here’s the foolproof way to tell if your ex is still hung up on you.

Ask.

No way. Yes way!

You’re an adult now, so why are you playing high school games? Just march on up and ask them how they’re feeling about things. Worst case scenario, you’ll end up with a black eye or bruised ego. (Okay, or maybe the target of a nasty blog post or Twitter rant.)

But the best case scenario is that you might get your ex back, and isn’t that why you read this whole article in the first place?
