You first have to figure out what happened in the relationship and then decide if your really want to get your ex boyfriend back.
You must be honest with yourself as to why he left.
Was it your doing or was it his? Who was selfish? Was there cheating involved? Was the relationship becoming stale or boring? Once you understand why you two broke up, then you must decide that you can fix any problems that lead to his leaving.
Relationships are hard because people must avoid a natural human trait which is selfishness.
If you think about it everyone is selfish in some ways, no matter who they are and even if they think they are not.
Selfishness is probably the leading reason why relationships break up.
If you think you can change then you have a chance.
But if it is your boyfriend that was selfish and left then it will really be hard to change him.
If this was the case, then maybe it was for the best that the relationship ended and it is time for you to move on.
If he cheated then you must really think if it is worth trying to get him back.
In most cases it is probably not a good idea to try to get the relationship going again, because there is a good chance he will cheat again even if you try to change whatever you think was wrong.
In relationships you must realize it is very hard to change the other partner.
Even though they want to change and they say they are going to change something, it may be hard for them to stick to the change and it will end up with him leaving in a few months or years from now.
After awhile couples get content and take for granted their relationship with each other.
The fire that was first there and attracted both of you in the beginning has flickered out.
The relationship has gotten boring.
For this you need to re-ignite the flames.
You have to learn to keep the fun there and try to always keep it interesting by experimenting with new and different ways to same situations.
Now, it is time to act since you understand "how to get my boyfriend back" because you have thought out the reasons why the relationship broke up in the first place.
Once you have figured out what needs to be changed by whom, it is time to contact your ex boyfriend and try to get him back.
Call or send him an email.
Just don't sound needy or wanting.
Don't cry or plead with him.
You will not win him back this way.
For the first contact just talk and try to have fun.
Get you points across and place no blame on him.
As soon as he hears it was his fault he will run as far away as he can and you will not get your boyfriend back no matter how hard you try.
Try to arrange a get together where both of you can talk and just go from there.
It isn't hard to get your ex boyfriend back if you can discover the faults of the relationship and why he left in the first place.
You just need to do your homework in the beginning to discover why the relationship ended.
Above all be honest with yourself.
If you can't be honest there is no way the relationship will ever go anywhere and you are just fooling yourself.
But on a positive note, there have been so many women who were able to get their ex boyfriends back just with a some planning and a little know how.
