If you keep thinking that you wish there was some way you could get her back, then the breakup most likely wasn't so ugly that you think there is no way to mend it.
For this to be possible you have to hope that she's thinking the same thing.
If things were said in anger or hurt that shouldn't have been said, now is the time to apologize.
Sincerely showing regret is a good place to start mending feelings.
There's still no guarantee you can get back together but showing her you respect her feelings and regret any hurt is a good way to begin gaining her favor.
Show her you miss her and are concerned for how she is doing.
If your first effort makes her angry, you'll have to change your approach until you find something that gets her approval.
Try to think back and come up with something she will appreciate or will bring back pleasant memories and feelings.
Instead of sending her a printed card, write her a note.
Try to get her to realize how you truly feel.
Being thoughtful won't necessarily get her back, but most women feel that their mates don't pay enough attention to them and don't try to understand them.
Being thoughtful to her on its own might not get her back but it is another step in the right direction to mending the relationship.
Just realize that you have to be patient and push too hard.
If she feels you took her too much for granted in the past, she will probably be skeptical about your concerned attention now.
Be patient and give her time to feel confident of your feelings.
Going slow isn't easy but getting overanxious could wind up pushing her further away and spoiling your chances.
While you are trying to show your patience and concern, it might be okay to go on casual dates with others, but if you get too romantic with someone else, you will probably kill any chance to get back with your ex.
If your ex-girlfriend already has a new boyfriend, the chances of getting her back are slim unless you can show her she'd be much better off back with you.
Being thoughtful toward her and patient can increase your odds.
Even if it seems she has already moved on, simply send her a hand written note wishing her well.
Don't seem to be expecting anything from her.
Your kind thoughts might surprise and really impress her.
The above suggestions are just the beginning of a proven system that can show you the actions to take to win your ex back.
A well thought plan can make all the difference for success when it is so easy in this situation to let your emotions over rule your reason.
