This doesn't just go for a romantic point of view, but in any case--you can specify if you'd like.
How do you feel about the two?
I can forgive but I can't forget. It's a fatal character flaw of mine.
I do give people second chances. I have given someone just that this year. So far they haven't let me down.
Does everyone deserve it?
No I don't believe they do. And only you can decide whether you think that person is worthy of it.
are there rules?
Yes, if you give someone a second chance, you have to be prepared to end it if they do the wrong thing by you again.
Do they go hand in hand (do you forgive AND give scond changes, forgive only, or give second chances with grudges held back)?
