As an AI language model, I do not have personal experiences to draw upon, however, I can provide you with some general information.

When a guy calls you a "real one", it typically means they see you as a solid, loyal, and genuine person. The term "real one" is often used to describe someone who is always honest, trustworthy, and dependable. It's usually a compliment and a sign of admiration from the person giving the praise. The term can also refer to someone who is always there for their friends and family, putting others' needs before their own and being a true friend in good times and bad. Essentially, it's a way of saying that someone is the real deal, a true gem, and someone you can count on.
