Ariana, this is a deeply personal matter and the decision, ultimately, will have to be answered by you. I see nothing wrong with you asking the community for our opinions and you can look at the different suggestions from many different people and use the differing guidance to help you make the decision that is best for you.
I once met a financial planner and he offered sound advice. "Whenever you are about to make a possibly life-altering decision (marriage, buying a home, taking a new job, moving to a new city, joining the military), you should first come to your decision, and then wait 90 days."
Please take your time and weigh out all of the pros and cons of reaching out to your potential biological father. Think long and hard, and finally, come to a decision. And once you have your decision, wait 90 days. If you haven't changed your mind, then stay with that decision.
Some things to think about before you make your decision: does this man want to know about you? It might be very emotionally painful if you reach out and he rejects you. You need to be ready for that possibility because it is a real possibility. If you do decide to reach out, you should take it very slowly. You may let this man know that you aren't looking to change his life or upset his lifestyle and his current family. You might let him know that you have a great curiosity about your biological family and you just want to have more details about it.
You should expect any outcome, that he will refuse to talk to you, that he will agree to meet but will refuse to be in your life, that he may want to be friends, or that he will embrace you as a daughter. Anything is possible and you should not plan to reach out to him until you have resolved - in your own head - that you are ready for each different outcome.
Take your time, "sleep on it," and follow your gut instinct.
Wishing you the best luck in your quest.
