I would have to find out “why” s/he said no and dropped you back then. That would make all the difference. If something “better” came up and they went after that at the time I would definitely not try again because I wouldn’t trust that person. If they weren’t sure it was going anywhere and they didn’t want to lead you on or were afraid you were more into it at the time than they were and were afraid you would get hurt, then yes I would try again.
There are many factors in shidduchim many times it is miscommunication and that is why many years later it comes around again. Or it just wasn’t the right timing the first time around. However, a leopard doesn’t change their stripes, so if it was for selfish reasons then be careful and don’t get hurt again. Try to get an honest answer.
