Winning an ex-girlfriend back can, in fact, be harder than winning a new girlfriend and often is unless you go about it the right way. There are websites which can supposedly tell you how to win your ex girlfriend back but even with their advice it may not be an easy task and so you should perhaps be sure it is the thing you really want to do before you even start. There are of course many times when we would want to but if the only reason why you want to is that you miss the female company, it would probably be easier to just find someone else. If however, you realized too late that this is the girl of your dreams and she could not be replaced, then you need to try and win her back and so be set for a trying time.
Most guys that try to win an old flame back will beg the girl to come back but even if she did after you begging, it would not last long as by begging you have shown her that you are weak, too weak to even try winning her back without resorting to begging and that will certainly make her lose respect for you once again cause a break up between the two of you. Some websites will also suggest that groveling can be bad but in most instances, at least a little groveling will always be necessary and so prepare to do some groveling if necessary.
The first thing you need to do is determine the reason why she finished with you as only, by knowing that, can you proceed with any hope of real success. If she is to take you back she will expect you to have changed or at least started to make those changes and this is one time she will probably not just take your word that you are changing, she will probably want to see some effort has at least been made. Now you may not agree with her reasons but they are her reasons and so you must suck it up and make the changes if she really is the girl you want.
We all like to have a girlfriend but sometimes we do not realize that one particular one is different from the rest, well, not until you have lost her at least. It is that realization that may make you decide to get her back and so knowing she is special means that you are prepared to make a few sacrifices and sure enough there will probably be one or two that you have to make. Getting an old girlfriend back is something you should not take lightly then as it will cost you something in some way or another. Regaining her trust is often a major part of winning her back and so do not lie, if that is what you had been doing before and try not to embellish too much either.
