After a breakup it's natural for a man to miss his ex. If you're in this situation, the first thing you should do is ask yourself if you really love her. If you do, you have some work to do. If not, it's best to accept your pain, work through it, and move on.
When you've decided to work on getting your ex back, your most important step is to plan your approach it. Too many men don't do this, and just jump into trying to win their ex back without direction. This leads to a sloppy approach full of mistakes that will push her further away. Decisions made in the heat of the moment usually turn out to be the wrong ones, and this is as true with relationships as anything else.
So allow yourself time and space to cool off after the breakup. When you can think clearly and objectively about your situation, it's time to figure out what to do about it. Until then, it's important to not make any moves, like calling her or dropping by. These kinds of things can be disastrous if you haven't planned out your approach and decided what to say and when would be the best time to say it. Therefore, planning your approach to communicating with her should be the first priority in your plan.
Beyond that, it's important to decide how you want things to go once you and she are talking again. How fast should things move? How close should the two of you get at first? Without preparation there are too many mistakes that can be made with stuff like that.
Therefore, making a plan and committing to stick with it is the first real step you can take to getting your ex-girlfriend back, and the most important.
