First of all, if you're not okay with being single, you'll give of a desperate vibe that will make it less likely for you to get laid/get a partner. And if you do get a partner, you'll be very vulnerable if you see her (or him) as the meaning of your life. Because if that's the case, you'll be devastated if you get dumped. I knew a guy who killed himself after being dumped by his girlfriend, and that is not uncommon. You shouldn't be too attached to what you're getting from the world. Focus on what you can give to the world. Because then, you'll be in control of creating a rich and meaningful life. You should still have interactions with women or men. But do it to challenge social anxiety, practice social skills and to have fun in the moment. Don't be too attached to the outcome. Let life surprise you.
