From my past relationships i have learned a very important lesson, that is you should never force anyone to do anything, especially the girl. If you are having trouble with your relationship, and it reaches a situation that it can not go any further, at this point never force the either to continue the relationship. Forcing someone to continue only makes things worse. By chance if you continue, it only going to get worse. If he or she wants to leave the relationship, let them because if they truly want to continue the relationship they will come back to you. And if they do come back on their own, then be sure, the relationship will only get stronger. Coming back on their own means that they have realized what had gone wrong. Forcing someone to think that they have done something wrong will only make them think that they have not done anything wrong. So next time you are in such a situation, be sure not to make such mistakes.
