I understand that usually, it's not considered a good idea to date coworkers, because it can lead to personal problems spilling over into the office and negatively affecting the company.
Why would you value the company more than your personal life?
The "issue" with dating co-workers is that if the relationship goes south then you'll still have to see them and behave professionally every day. That's all.
Date who you want, be a professional at work if it doesn't work out (or also if it does), and there's not really a problem. It's honestly that simple.
