If you dumped your girlfriend and now you realize what a terrible mistake you've made - it's ok! I know how you feel - you are probably pulling your hair out right now because she refuses to talk to you and wants you to stop calling her.
If you are really serious about winning your girlfriend back - you will need some patience! It's not impossible but there is no shortcut here! So I want to tell you what exactly you should do to get back together with her as quickly as possible! Deeply apologize to her - after breaking up with her you need to show how that you regret! Even if she is dying to hug you again, she has some pride and self esteem.
Another thing she has is pain in her hurt! If you can make some really special apology it could be great but sometimes just expressing your feelings will be enough! Make her trust you again - I think you know that nobody will touch a hot iron twice and that's why it's not easy to win your girlfriend back after dumping her! Right now she doesn't believe you and afraid of being dumped again! That's why she is trying to reject you.
Make her feel loved and special again.
Show her she is the only woman for you and it will be probably enough! Final tip - give her the time she needs to forgive you.
It won't happen in one day but if you really love your girlfriend - it will pay of! I hope my article was helpful, good luck!
