Do i keep on holding on or let go of my ex?

first remember you did nothing wrong. second sit down with him and talk it over, if he really loves you he will be with you, if he doesn't want you, he doesn''t want you, and nothing will change that. i realize you love him but it may be time to move on. i hope everything works out for you, just remember that's it's gonna hurt for awhile but in time you'll move on. you listen to your heart and you'll be ok.
