I won't say move on, or don't cry. That's bull crap because I know how hard and painful it is! You might think it's the end of the world, that's what you're going to believe for a very long time. But believe me you'll get over it! Maybe not now, but you'll get over it! You think she'll come back if she sees you like that? No! She won't come back anymore, or if she does, she doesn't deserve to be accepted by you AGAIN! I don't know what happened between you and her, but cheating on you is WRONG and will ALWAYS BE WRONG! Based on what you said, I'm pretty sure you have a big heart and you have so much love to give! It'll take time, but I tell you, it's worth it! Dude, you just lost her, don't lose yourself too! If you think she's the perfect girl for you, fine! But at least give yourself a chance to meet the 'right' girl for you! You obviously know how to love someone, this time you should learn how to love yourself more! God bless you and HER! Good luck!
