Your ex may have broken up with you and it's been a month after you have realized how much you love your ex and that you find it hard to go on in your life without him. In general, if your ex has played an important part in your life, it'll be really hard for you to move on. If you know in yourself that you can't go on without having your ex back in your life, then you should drive your ex nuts to make him go back to you.
