If i had a chance to Should i?!?!?!?

Fiance? You are THIRTEEN years old!

I dont think you should go out with him again, if he cheated once, he doesnt deserve another chance.

You are way to young to be engaged. You may think it's not that serious, or that you are mature enough to handle it, but trust me when you get older.. man, you'll look back and be like "Why was I that stupid?" It's okay to have a reltiaonship at thriteen, but it's way to young to get attached like that. You have your whole life ahead of you.

I know I just went way off topic but I just had to say...

Take Care :-)
