Getting your girlfriend back can either be a good thing or a bad thing. Regardless of why you broke up, there were obviously problems that caused the relationship to fail. If the problems were due to compatibility issues, you may want to cut your losses and move on. However, if the reason why you broke up has to do with you not being the best man you can be, then there may be hope for you.
There’s no use moping around after a breakup. If you want your girlfriend back, you’re going to have to man up and be better than you’ve ever been. Your time away from your ex-girlfriend should be spent on making yourself so awesome that she’ll regret ever leaving you. To do this, you’ve got to visibly improve yourself. A good place to start is to hit the gym, build a new wardrobe, and get a new hairstyle. When you’re looking good, your ex won’t help but notice how sexy you’ve become.
Now that you’ve got your new look, you should also change your life in other areas. You could go after the career you’ve always wanted, take up a new hobby, make a bunch of new friends, and ultimately build a life that you enjoy. Ideally, you want to create a life that you can appreciate and enjoy at all moments of the day. This is a difficult thing to do, but when you actively work on your life you become a happier person. Most people, including your ex-girlfriend want to be in the company of a happy person, so be that person.
Lastly, date other women and genuinely get to know them. Once you’ve made the effort to improve your life, you may find that your ex-girlfriend was not as important to your happiness as you thought and that there are other women who are a better match for you. Alternatively, after dating a series of women, you may find that your ex-girlfriend is the best one out of all of them. If this is the case, you’ll have a better chance of winning her over again now that you’ve improved on your life.
