Even though your boyfriend is now your ex, the thing occupying your mind the most is how to get boyfriend back.
Well don't give up! There's actually a good chance you can get your ex back if you pay close attention to these five points:

1. First thing, get clear on why you want your ex back.
   Is it because you are depressed of don't like being alone? Or are you still in love with him? If you are sure your reasons for wanting him back are good ones, keep going.
   
2. Make sure you are giving your guy some space.
   Don't keep contacting him or showing up at his favorite places.
   Give him room or you will come off as weak, needy or maybe even a stalker and make your job that much harder.
   
3. Spend some time thinking about what went wrong in your relationship and what part you played in what happened.
   If you two are going to get back together to stay, you need to understand what happened, and you are going to have to change the things that you did that contributed to the problem.
   
4. Give yourself a month or so to deal with the preceding items.
   Then arrange a meeting with your guy.
   Tell him you still care and would like to talk to him.
   
5. What happens next depends on how he responds.
   If he says he still cares for you, that's great.
   If he says he doesn't have feelings for you anymore, things get harder.
   The thing to do is wish him luck finding happiness with someone else.
   This will be real hard, but is the best option for this situation.
   

These five ideas will help you get him back.

There is so much to do to win your man back that a guide will be an immense help.
But whatever approach you take, I wish you the best possible luck.
