Mazal Tov!
I don’t think there’s a silver bullet answer to your question. The topic of matchmaking is a rather complex one. Just think about the fact that according to chazal, Hasham is –since he completed the creation of the universe– sitting and matchmaking. Think about this for a second, Hasham who created such an incredible complex universe, so complicated that we hardly touched the surface in understanding it, think of laws of physics or perhaps more closer to home, the human body (all its organs, the millions of lines of code in trillions of cells), a creation we will NEVER truly begin to understand, yet, the same Hasham is sitting and matchmaking! How complex must matchmaking be. Do you believe its Hasham who matched you up with this boy?
I can give you a loooong deep philosophical answer on opposite gender gravitation and the philosophy behind it, but i doubt you care. The bottom line is, one can never learn about another person until they live and spend life together. All the dating in the world wont get you near the results. People can date for months and months and yet still be in for an unpleasant surprise.
Btw, how old are you and the boy?
