Oh Kia...hun am so sorry. Remember IT'S NOT YOUR FAULT...It's not you. It's him. He's messed up and you can't fix him.
You're worth so much more. It might not seem that way now but he's kinda done you a favour. You could have spent the next 5 years waiting for him to change and the whole time he could have been cheating on you, lying to you, making you think you were crazy. He's brought an end to it for the both of you...his actions have set you free.
Take your time, mourn the loss of the "dream" but really try and keep your focus and see him for what he really is.
Keep posting. *hugs*
