"It's not you, it's me", "I need space", "I just need to straighten my life out before I think about relationships".
If you heard any of these excuses from your ex, I want you to understand one thing: They are ONLY excuses.
The main reason your ex dumped you was because they are no longer attracted to you.
Think what you will, but if you are attracted to someone enough, you will move heaven and earth to be with that person.
You will forgive just about any wrongdoing to make the relationship work.
Granted, in some cases restoring the attraction is not likely, or even impossible.
If you were abusive, a habitual cheater, or anything like that, you should probably hang it up and move on.
You probably don't deserve your ex anyway.
But, for the most part, the loss of attraction is usually attributed to boredom, your relationship fell into a rut, or you just lost appreciation for each other.
In any case, these can be fixed as long as you know how.
A few ways that will assure you don't spark attraction is by begging, pleading, and chasing after your ex.
This will not bring your ex back.
If anything, it will only strengthen their resolve, and make them comfortable in their decision to end the relationship.
You can't, whenever in contact, continually rehash what went wrong in your relationship.
That stuff is a real downer.
What you need to do is to be fun again.
You have to be someone your ex WANTS to talk to, WANTS to see, WANTS to be around.
This is only accomplished if you are a fun person and it's nearly impossible to be that fun person when you are stressing so much over a broken heart.
