Always lift yourself up and take a look at your belongings and your good qualities. Try to improve them and concentrate on your weaker points and work hard to make your weak points lesser. Show confidence in pursuing your partner and if he/she realizes who you really are, then he/she might be influenced to respond your chase of his/her. Winning back his/her love will no longer be your prime effort if this happens, he/she will also put her own pains on the line and before you knew it you did win back his/her heart and he/she will be in your arms once again.
