Not to downplay your situation. I assume you're still young. But life is full of choices. There's no way to know which is the best choice at the moment. All you can do is make a choice, give it everything you got, and you won't regret it. I promise! Just like you are doing with your start up. As for finding the right girl, don't worry the right one WILL come, just when you least expected. In reality, there isn't just one right one. Just as you are not attracted to just one girl. Any relationship requires (much) effort to make it works; just as your relationship with your startup. You are just not ready for a personal relationship now. But that should stop you from going out and having fun with friends. And when you are ready, one of those friendship will turn into a relationship.
