What can I do?

Duckie told me that if I decide to leave him, he will stay strong, and live on, and hopefully, he will do something great to the world.
Honestly, I am happy for him, that he can take care of himself, and at least, I know that he will not hurt himself anymore.
However, that also tells me that he doesn't value me that much anymore.

I really love him. I don't know what to do. Is that the end of our relationship, after 1.3 years?

I don't want to lose him. I really wish he can value me a lot more.

What can I do?

I guess I will do that too. I have to keep working, and I know that, if I leave him, I will be happy. Perhaps, someone else will value me more. ^^
