There are many mistakes you can make right after a break up that can ruin your chances of getting your ex back.
On the flip side there are a lot of things you can do to greatly increase your chances of getting your ex back and even have them chasing you wanting to get back together again.
Accidentally coming off needy After a break up, emotions are high and it's not always easy to think rationally...
A lot of people make the mistake of coming off desperate or needy and it really pushes their partner away even further.
During this time you do not want to send any desperation signals that your ex may find annoying or just plain sad, instead you want to display more of a positive attitude (at least around your partner) and go along with the break up at first.
You also don't want to have too much contact with your ex if at all directly after a break up.
You should give them some time to think and give them a chance to begin to miss you; they'll start feeling different when the reality sets in that they may never see you again.
Trying to Force things Many times when things are getting a little bumpy in a relationship one person may ask for a break or want to end things and the other person may get upset and even start arguing about the break up...
This will not help the situation, you can not force your ex to get back together.
If things ended poorly you should try writing your ex a letter, not an email but an actual letter, this has more of a personal feel and will get noticed in today's digital age.
