I agree that post-college life is just so much better in every way. You have a career, an income, a trajectory you're working on. New hobbies, new skills. More travel, assets, maturity. As a man, 20s dating is better than college, and 30s dating is even better than 20s. You're just going through a transition. Try to live in a populated area with other young people. Are you in a big city? Time to break out of your sheltered shell.
