move on and marry someone, don't wait for me
It has been years, and I've waited, but nothing has happened. I don't understand why you keep waiting for me if you aren't going to do anything. If you've been quietly watching me all this time, know that I've noticed you too.
There's something I need to tell you. I've been diagnosed with a disease, and it has changed the way I look at life. I don't want you to keep waiting for me because I know there may come a day when it's simply too late.
Please move on. Find someone who can give you the future you've always dreamed of. Get married, build a family, and live a happy life. I don't want to remain just your "long-time crush," the person who makes you smile whenever you see me or hear my voice, but never becomes part of your life.
If you never intended to approach me, then please stop asking people about me. We both deserve the chance to move forward instead of living in "what ifs."
