If someone is trying to demand an apology from you years later, is that person a loser?

She was still stuck on the time we were HS freshmen. It's been nearly 9 years already. Honestly, I have no regrets about anything. She sent a random message saying if I remember her and ''don't you have any regrets''. I didn't like her back then and now with her recent message, it makes me dislike her even more.

My reply:

I see you haven't changed. All you have done right now is reconfirm my opinion about you Ann Marie (fake name); you're still the same sore loser. Always have been and always will be. It was such a blast back then. You ain't ever getting any apology from me. I regret absolutely nothing. Later
