To be honest it sounds as if you are playing games with him. No contact isn't about getting your way which is what it sounds like you were using it for. Darling you dug this hole all on your own.

...

But that's not what its for. You were shutting him out of your life for days at a time when you are in an active, happy relationship. Shutting someone out is not the way to get things to change. Why didn't you just have a rational conversation with him about how you feel? I can tell you if a boyfriend did to me what you did to your boyfriend I would walk away and never look back. Your behavior was very immature and hurtful.

Give it a rest with the constant bombardment of messages to him. Leave him alone for a week. Then I'd say send him an email apologizing for your behavior and explain why you did what you did. I'm not saying he will forgive you and want to start the relationship again but you will have at least given him a chance.
