Here's how to not only get over your ex but to get them back with the least amount of work on your part.
It might be that you did not actually mean to fall in love with a partner, but the relationship developed over a year or so. Naturally, two people can quite easily become fond of each other and in general, even if you begin to argue, the bond between the pair of you will continue to develop. Of course, this bond can soon be broken and you could find yourself all alone and feeling quite insecure. Of course, some relationships have some valid reasons for parting, where as others simply don't.
It might be you have cheated on your partner, in which case, you should feel guilty and technically they should not take you back. If however, you feel like you are still both in love, but it is just the arguments and similar that are ruining your relationship, then you certainly have a good chance of getting your ex back. It can be an extremely depressing time of your life, but don't give up. There is plenty of help at hand and all you need is time, effort and commitment. You can have your ex back in your arms within 7 days!
Making sure you have a positive outlook on life is actually more important than most people think. Nobody is interested in a desperate or needy person, so make sure this isn't what you become. If you're feeling down, confused or tired with life, then do physical exercise. This releases endorphins than combat depression, so could help quite a lot!
