People direct movies about people like you.
You are going to be one of those old ladies who say
"I loved that boy so much. I loved him with every piece of my heart and he couldn’t even see it."
You will be sat on a bench watching the sunset and you’ll meet a younger version of yourself. They will be wearing the same look of despair you have right now and you will give them some advice.
"Stop wasting your time on someone who doesn’t care." You’ll say.
"They might seem like they are completely right for you, but believe me if you get up and walk with a sense of purpose, you’ll meet someone who is infinitely more suitable.
"He is going to sweep you off your feet and gosh, you are going to be glad for this situation, exactly as it is."
And you will smile, because you have met this someone and he is at home baking cookies for your 50th anniversary.
