Well if Cody's friend is a nice guy you should totally go for him. Who cares what Cody thinks as long as you have a chance to be happy. :P He was a jerk for leaving you in the first place, for a stupid reason, so don't go back to him~ Maybe hang out with that kid and see how things work out. You don't have to say yes to dating him right away, just see how you feel about him as time goes on. :3
*nod* I learned my lessons when I was younger, don't rush to the next person, especially so soon. Take your time, get to know him first, you need ot know you can trust him enough to go out with hi,
Well this is a bit too soon after you lost your other boyfriend, you have to take it slow, that's the only right way to do it. Dont go out out, but I would recommend finding time to talk with him, just do random things for now until you're sure about it, mk?
