A tactic is a maneuver for attaining a specific goal. In this case, the goal is winning your ex back and mending the underlying cause for breaking up.
1.) To begin with, you will need to slowly bring her back into the relationship. An injury does not mend overnight. A little time will be needed to mend your broken relationship.
Instead of attempting to repair things as fast as possible, you'll have to figure on a month to let things cool off. While you're waiting, you should be sizing up the relationship itself. Think about issues such as whether you really do want her back and personal changes that you will make to get the relationship to work.
2.) When this cooling off period is over, you'll have to find a way to open up the channels of communication once again. It is vital that you build up a good degree of comfort and ease with her. This basically means being a good friend and being able to converse with her in a way that is relaxed.
You shouldn't have any talk about serious issues that puts her under pressure. Now is not the time for discussions about the separation or other difficult topics. There will come a time for this sort of discussion but it will have to be done later on.
If it seems impossible to establish a friendship, then you'll have to allow more cooling off time. Nonetheless, one month really ought to be the maximum. Excessive time apart will allow your partner to get comfortable with living without you. In addition, it increases the chances of another boyfriend to enter the picture.
3.) A time will come when the important matter of continuing the relationship will have to be talked over. This is going to be a very nerve-wracking time. Nevertheless, you can't afford to be squandering excessive time as her friend. If there's no possibility of convincing her, you've got to find this out so that you can get on with your life.
Don't be putting too much hope in her agreeing right away with resuming the relationship. A response that is non-committal means that the prospect of restarting the relationship is still on her mind. It will simply require some more time for her to know either way.
4.) A tactic to try out is to exploit something that everyone has done at one point or another. What I'm talking of is the inclination that we all have to play back emotional events several times over in our heads. When a person says something that induces a very powerful emotion, we like to replay that moment over and over in our minds.
This is the way that we process our feelings about a specific emotional event. Usually, this happens when someone unexpectedly makes a snide comment that takes us off guard. But, this can also be triggered with a totally unanticipated compliment or dramatic gesture.
In order for this to work, you will have to elicit a very strong positive emotion. This has to be a compliment or gesture that she would never expect to get out of you.
If you succeed in this, she'll be enjoying this repeatedly in her mind when she is by herself. Her good feelings about you becomes strengthened and reinforced with every "play-back". You probably won't be able to induce this state more than a couple of times, but one or two times is all you'll have to do.
Skillful use of these tactics should help a lot in your efforts to get your ex back.
