Apology Letter For Ghosting
Dear {Recipient},
You probably weren't expecting to get a letter from me, but I've always felt bad for disappearing on you back then. So here I am now, offering you my sincere apology--I know it's {number of} {weeks/months/years} late, and I'm not sure if you even want to hear it, but I'm sorry. I'm sorry I ghosted you.
I know it sounds so cliche, but it was me, not you. And I didn't have the guts to tell you, so I dipped.
I'm not expecting a reply or anything. I just wanted to let you know how sorry I am for ruining our relationship. I hope you're happy now and with someone who treats you better.
Sincerely,
{Your Name}
