Why would your ex-girlfriend whom you dated for 5 years say she needs a little time to get her life together and then refuse to talk to you or see you?
It doesn't matter, let her go. She doesn't want to be direct and hurt your feelings. She doesn't want you. she probably still has deep feelings for you so seeing you can cause her pain. GO SEE HER!! Surprise her with flowers and something that she likes. If she declines at that point just consider it a wash and it's over.
