Remind Me To Forget Lyrics Meaning

Maybe it's a relationship between a couple, and I guess one of them is always cheating on their loved one, but they don't wanna let them go, but the other person in the relationship does and is done with what they had to put up with...

Like this part, "It doesn't matter where you are, you can keep my regret.. "

The person wants them to know about them regretting the fact that they fell in love with the person in the first place.

"Remember I told you
To save it, it's over
And I'll be alright
So hurt me as much as you like
I need you to let go
I got these mementos
And I'll be alright"

I guess in this part they're saying that the person breaking it off doesn't want to hear the apology it what they have to say, they want the person to let go, even though the person that's breaking it off still secretly has feelings for them, although they have be hurt all these times.
