If you and your ex are separated, I have good news. Over 90% of relationships can be fixed, even after you've broken up. The trick is to act quickly and follow a few simple rules.
First, you should always act naturally. If you act like you are desperate to win your ex, you will never succeed. Think about it. When you first started dating, you probably did not follow her around or call her all the time. Instead, you may have played a little hard to get. You were probably friendly, but not over the top. This is the way you should act now in order to win your ex back.
Second, make sure to work on yourself. If you want to win someone over, you need to be worth winning. You need to put yourself first for a little bit. Exercise, eat well, go out with friends, and find hobbies to do that you enjoy. If you do this, you'll make yourself a more interesting and attractive person, one that your ex wants to be with.
Third, be nice. Don't talk about all the bad things your ex did to all your friends. This is bound to get around and cause you problems later. Make sure when you see her, you are polite and pleasant to be around with. You want her to remember you as a good person, one that she wants to be with. If you are negative all the time or make her feel badly about herself, she's not going to want to be with you.
To build up your mind, you need to change your mood from negative to positive. It is very common to fall into depression following a break up. But that negative thinking will come across to everyone around you. And generally, people will drift away. They don't know what to do with that negativity, so they just stay away from you.
To fix it, you'll need to focus on thinking positively. Whenever you find yourself thinking a negative thought, replace it with something positive. Also, try thinking positively about what's going to happen in the future. Other people call this "The Law of Attraction," and find it actually attracts positive outcomes for them.
Next, work on your body. Exercise and diet can help you feel good about yourself, relieve stress, and make you more attractive to the opposite ***. Try to eat a healthy, balanced diet, and work out at least three times a week.
Finally, work on your personality. What you need to do is make sure you are interesting to be around. Try taking up new hobbies. Go on exciting trips. Just get out and do things, and you'll find you have plenty to talk about. Interesting people are more fun to be around, and you will find other people hanging around you more.
