Most Helpful Guy
Well... you are going to HATE this opinion... but the chances that it would work out the second time around is 0.01%. I'm sorry, but that's the way it is.
BUT... my guess is that you already know this. From your profile picture, you are a beautiful girl, and the fact that you even "question" giving someone that did you wrong a second chances tells so much about you ability to care for someone and find the good in people and in life. It's too often that girls with those type of personalities get hurt over and over and never have the chance to be happy... because they just keep giving that "second chance".
I think it's time that you have your FIRST chance at being with someone that will treat you with respect, loyalty, and give allow you to have 100% trust in them. And this cannot be that guy... it simply will never work. And again... you already know this.
This guy may love the THOUGHT of you, but if he truly loved YOU, he would not have done what he did... period. No matter how you flip, spin, or twist it... that's the fact. Would you have do the same thing to him? Why not? Because you loved him? Now that makes sense doesn't it?
The biggest disadvantage now is that he's going to play on your kindness until he convinces you to do what he wants.
Now to be fair, there is that 0.01% chance... however small that is... it's still a chance. The ultimate choice is yours regardless of anyone's opinion. You have to be happy with your choices. You can always give it a try if you can stand the potential for additional pain and time lost with the wrong person.
Personally, I would move on to the better quality that you deserve. But I'm not you, and you need to decide for yourself. Good luck in whatever way you walk from here.
