News flash! When a boy breaks up with you, it really just means that he's testing you: he wants to see how much you're willing to go through to get back together with him. Boys want to feel loved, too :]

Let's go through the basics:

1. There's a really good chance that he "broke up with you" because he thinks you're getting a little pudgier than you were when you first met. The fastest and easiest way to solve this is to take more "frequent" "trips" to the "restroom." If you need help, just make sure to wiggle your fingers :]

2. Another reason why he might have "left you" is because you're not talking to him enough! Do you know why he didn't pick up the phone after the tenth missed call? It's because he was waiting for the fifteenth missed call! Don't stop when the finish line is in clear sight. Keep sending him those angry, then sad, then angry text messages, keep a close eye on his availability on gtalk, and keep posting pictures of the two of you on his Facebook. PROTIP: When you "Like" things on his Facebook, there's no way for him to remove it :]

3. Make sure he knows how special he still is to you. Social networking has made this tremendously easier! Closely inspect any new friends he made on Facebook (you want to make sure they're sane!), narrow down the search filters to find his OkCupid profile (you want to make sure it's appealing!), and frequently check out his Yelp activity to see where he's been hanging out lately (you want to make sure he's enjoying himself!). And don't forget to keep close tabs on that keylogger you installed on his laptop. But don't tell him. Boys love surprises.

4. Perhaps the most important thing to keep in mind is that you want to make sure he feels safe and comfortable around you. What you do in real life will mean much more than what you do online. Since you guys work together, make sure to position your seating so that you can see every single thing on his monitors. This way, you can warn him to close his NSFW tabs when the boss is creeping around. You're his savior! Luckily, this will take up the majority of the day and he can always feel safe around you.

After work hours, it's a little different. Every other hour or so, drive slowly past his place to make sure there aren't any unfamiliar cars parked anywhere. If you do see any unfamiliar cars, look into (or sneak through!) his window to make sure that he's not having any unwelcome visitors. Again, you want to make sure he's safe. If you happen to catch a stranger (you might have seen this person try to befriend your ex on Facebook) harassing him - whether it's on the couch, or the floor, or even the bed - you'll want to make sure that you're properly equipped to "confront" this person and defend your ex. When you're done "confronting" the person (and you've properly cleaned up any of the mess!), you can use any of your remaining energy to retaliate (in self-defense!) should your ex respond negatively from the adrenaline.

Anyhow, sorry for the wall of text! I really hope things work out!

tl;dr - (1) more bathroom visits! (2) more text messages! (3) more social networking! (4) more looking out for him!
