Is it too late to say you're sorry?

I was reminded of an ex fiance while on the internet. I popped her name into a search engine and discovered she is a successful real estate agent. I was on the wrong end of the breakup and realize now that she was justified. Should I apologize for being an as*h*le or just let the dead stay dead. We both have families and live thousands of miles apart

let it go,as long as you know in your heart that you are sorry,plus you both have moved on,but if you ever run across her physically do apoligize.
