Love Infinite

Is it wrong to still have feelings for someone you haven't been with in almost a year?

I'm completely over what happened, but when I think about it, I find myself still infatuated with her, 

I have no plans of trying to enter her life again, or even if she'd let me into it. I don't want to ruin or put any kinks in anything she has going now, but I sometimes feel like I ruined something that could have been more.

I guess I have to make changes to my mistakes and not look back, but I know, I'll never lose the love I had for her, its something that will always be with me even if it doesn't stay with her.
