I would love...

I'd love to be able to say I DON'T LOVE YOU!!! but I can't...actually I can... I just can't forget my memories with you... I don't know why but they're such important for me and they make me feel bad because that remind me that you sucks, the worst is that I might gonna make somebody feel bad and I know this person doesn't deserve it.
I'd love to be able to tell some special and important person for me "I'm sorry" and he could understand me.
I wonder to know what is correct and how don't make this person feel so bad.

Could you tell me something?

What's better?

Make happy to some special person with something you know it's wrong?
or tell to this person the true although you know he's gonna get hurt?
