Wanting to get an ex back is like a knee jerk reaction after a breakup, especially if you were the one who was dumped. However, you have to understand that in this emotional state of mind, you aren’t really in control of your emotions to actually make a good decision about your life.
First of all, you need to think why you want them back. Just generic responses like “I love them’ or “I can’t live without them” or “We were really good together” will not do you much good. We often use these statements to avoid the specifics. You have to be more specific. What was so different about your ex that you can’t find in anyone else? Sometimes, it is better and much easier to just move on than trying to hold on to someone who isn’t really that great of a person. Most people fall under the illusion that they are in a deep meaningful relationship even if the relationship is just a couple of months old. If you went out with your ex for less than 3 months, then you really need to rethink about getting back together. Of course, if your relationship with your ex was toxic, then you should definitely stay away from them at all cost.
On the other hand, if you think that you two had a great relationship and had been together for a long period of time, it will be different for you. If you two had been married and had children together, then maybe it will be different for you. It is in these situations that you should put in the effort to recuperate the relationship because it will be worth it.
In essence, you should know it deep inside if your decision of wanting your ex back is really worth it or is it just a knee reaction to a bad breakup. Remember, there is no one who knows your story better than you, so it will be best to decide yourself.
