Some guys and girls were made for each other and perhaps can be soul mates but sometimes not both of them realize it and so one may break up with the other. In an instance where the girl dumps the guy and the guy realizes that that ex-was really the girl meant for him, he will try and win her back but be successful in doing so is often not very easy. It may seem easy at first but unless it has been done the right way, the success may be short-lived and she soon dumps him again.
Often a guy in this situation will have the urge to beg the girl to come back but if they do that, they will probably lose any chance they may have still had to make it a lasting relationship. According to websites which specialize in how to get your ex back and other experts, when a guy begs a girl to go back to them, although she may, she would have lost respect for him as he had resorted to begging which means they go back to them because of pity and no other real feelings. Of course, the pity soon wears off and that just leaves the lost respect to the girl once again dumps them.
In almost all cases though, the guy will have to have made some changes in their attitudes or behavior and those changes will have to be permanent or be kept for at least as long as the romance lasts. If a guy does not stick to the changes they made then the girl will often once again reject them but this time it will be even harder to get them back as they will then believe the guy cannot change.
If a guy thinks that the reasons why the girl dumped him were trivial or based on fiction, he should probably keep those thoughts to himself as she often will be convinced otherwise and think the guy is trying to make her look at being at fault which will never stand well with any girl regardless of how true it may be. The guy must always, therefore, be prepared to apologize and accept blame.
