Maybe someone told you that making your ex jealous will result in you getting back together with your ex, and maybe this seems like a good idea right now.
Let me tell you though - go through with this, and your chances of getting back together with your ex will be gone for good! Your ex is not staying away from you now because he/she doesn't love you anymore - on the contrary, your ex is hurting really badly right now, because of the things that you said and did, that's why.
So, instead of making the very, very big mistake of thinking that making your ex jealous will get you back together again, be clever, and just leave your ex alone for a while.
Your ex is also very confused at the moment as well.
He/she is very angry after the argument you had, and is not sure whether to get back together with you again or not.
Making your ex jealous will ensure that your ex decides on the latter option, for sure.
You see, the thing is, if you take on another partner with the idea of making your ex jealous, not only will you succeed in making your ex jealous, but you will also give your ex the impression that you are not interested in him/her anymore, and your ex will definitely not trust you anymore, either.
Three things will happen afterwards.
Your ex will carry on with his/her own life, the person that you used to make your ex jealous will be hurt, and you will be left totally alone, which will be all your own doing, of course, and whoever gave you this really stupid advice in the first place.
So, as you can see, making your ex jealous is an absolute no-no if you want to try getting back together with your ex.
Simply give your ex time to get over the break up, then make contact, and the chances are really good that you and your ex will be getting your relationship up and running again.
