The jealousy factor is well known as one of the best of the different ways of how to make an ex boyfriend want you back. Basically, if you dated for even a month, there is probably so emotional attachment still there. Your job is to dig it up without getting to close to him. He'll start aching for you back and won't stop until he has you.

Little does he know, he'll be playing right into your arms.

It's unfortunate that a single article couldn't possibly give you all of the knowledge you need to strike a nerve in your ex boyfriend that makes him need you around again, but there are places to get it.

Make sure that you don't come off as desperate in ANY way. If he thinks for even a second that you're just trying to get him back - he'll feel in power and even if you do get back together, it won't be the same. In fact, you might not even want to be in contact with your ex boyfriend... but do stay in contact with his friends.

Some girls think that it would be a good idea - or even cute - to figure out where their ex bf is going to be and show up there just so they can talk to him. That's a horrible idea and you shouldn't do it. Instead you need to make him want to find and be around YOU.

It is also quite common to think that you need to play hard to get, but that's not true either. You shouldn't have to make your ex WORK to get you back, they should just WANT you back. So are you serious about getting back in a relationship with your ex boyfriend?
