But no risk means no reward. I'll take the chance. Most important is your gut feeling, which isn't specific and is hard to quantify. But it should always be honored. When you ask older people to look back on their lives and tell you what they regret, often they will tell you that it ins't their mistakes or failures they most regret, but the risks they were afraid to take.
Life requires risk.
And so does love. It doesn't matter who you love, or where you meet this person, or how many people you must date before you find the right one. What matters is that you don't shut down, and give up, and live a fear-based romantic life.
