Like every lie people tell themselves to feel better, romanticism, too, has it's limits. It has a tragic funniness to it. What if the one simply doesn't show up? What if you just don't find the one? What if love just simply *doesn't* happen to you? Romanticism, believe it or not, doesn't have an answer to that. You can ask the most romantic people about it and suddenly you get hilariously unromantic answers:
You should work on your appearance, because there will always be someone who loves you just the way you are, except if you look like that. You have to adhere to beauty standards, no matter how stupid you think that is and how much that is not who you are.
Maybe you should try online dating, because love simply finds a way, but sometimes that way involves the commercial interest of companies that profit from keeping you on their platform by keeping your hopes up while not actually finding you a long term relationship.
Just give it some time, it *will* happen to you. Sure, others in your age have had their partner for more than a decade now and will have spent more of their limited time on earth happy, but you will probably ... be much happier than them, ... because ... reasons.
My life is a joke about everyone else that only I get.
