I ghosted someone for 2 years
Why did you ditch them for so long?
I hated lying to this person, now the truth is known.
You should be sorry for ignoring someone for so long. That person doesn't deserve to have been left wondering "why" for two whole years. You need to own up and apologize for ghosting them, and for whatever lies led to that decision in the first place.
There is no prize behind all this. I did it because I can.
I understand that you probably won't gain anything from fixing this issue, but it's still important to be honest and respectful.  You wouldn't want someone to treat you this way, so you should set a better example for others to follow.
