Someone once asked...
Someone answered with kindness...
If you really never want to get married. I suggest building yourself financially strong. You'll need money to support yourself in the future. And saving up is a must. Plus, make sure you're emotionally there for it too. Obviously as humans, we need connection, and being lonely is one very awful thing. But that won't be a problem if your bond with yourself is strong enough that you can sit with yourself, enjoy things alone, support yourself when needed. Even the people who get married sometimes, divorce, and start living alone. Which in case, are my parents only. Marriage isn't a guaranteed company for life. And I also suggest keeping your friends close too. But if you really do consider marriage, be it the person who gets you and isn't just your "I don't want to be lonely" person. Hope it helps.
