The first thing to do how to get a guy like you more is to let all your emotions out. Surely, if you want to get your ex-girl or boyfriend back, he or she means a lot to you then you must love her/him, very much, so you are hurt badly. Well, shout let it all out! Do not be afraid to cry if I want to. Perhaps you want to have a smoke or a drink even if you never did before? Well, it won't do you any harm. Just don't fall into hard drinking, because that way you will never have a chance to get your ex back.
