Getting an ex-girlfriend back is never easy and is often harder than winning her in the first place. This means that if a girl finishes with you, you had better think very carefully as to whether or not it is worth the effort it is going to take to get her back. Of course, in many cases, the guys think it is because they realize that she really was the girl for him and so there could be no substitute. If this is the case you had better think of a plan on how to get your ex back and hope that it works.
All too many guys think it will just be a case of begging her to come back using a lot of groveling. Whilst groveling may certainly help, begging should always be avoided as the girl then thinks of the guy as being weak and that will stay in their memory and one day, perhaps soon, may cause for the two of you to split again. So, grovel by all means but never actually beg as even if you do get together, it is doubtful it will last if she came back because you begged. Especially if your begging caused her to come back to you with a feeling of pity.
The girl will have her reasons for finishing with you but she may not have told them. This can be awkward as before you can gain her back, you have to fix what was wrong and if you do not know what was wrong, that is hard. You must, therefore, determine what the problem was before you can proceed with any chance of success. Once you have established what the problem was, you can then work on fixing it if possible.
I may be something small, to you at least and therefore easy to fix but to her, it may have been a big deal and could be overjoyed you made the effort to fix it. Of course, though it could be the other way around, something she thinks is easy to fix but in reality isn’t that easy. To be successful though you will have to find a way to prevail at any cost in order to win your ex-girlfriend back and this time keeps her.
