I do not think there are any rules for when you can fall in love or how long it takes. For me it was easy to let infatuation and sexual attraction dominate my feelings and then I would be heartbroken when it didn't last. On the other hand my sister fell in love at sixteen, got married at 17 and is still happily married 19 years later. In the end true love will continue, infatuation seldom does. Nothing comes with a guarantee. We are all different and the attraction between people is different in every case. No one can set your agenda for the man you love. I wish you well. Time will tell. Follow your heart if it continues to feel right
