whats the difference between "i move on" and "i forgot u already"

I think speaking on moving on is accepting what had happened, maybe did have a lesson learnt, and move on to a new life. I forgot you already is more of a lie. Of cos you didn't forget him, and you won't forget him. It won't make the other person feel better or worse.

Yeah, I agree that moving on is hard to do. We get lots of advices telling us to do this, and do that, so on and so forth but when it comes down to it, still easier said than done. It is really hard and wouldn't happen after just a day or two. And it still depends upon the person. Some succeeds in moving on, some just get tired trying. About your question, I think that when you say "I've moved on", you mean that you can face him again and live your life with or without him. But when you say "I forgot you already", it means that you don't even remember now that he exists.
