Answer:
There not as diffeent as you might think your teenage crush is young they probably do not know who they are themselves teen hood is about discovering who you are what you like this is similar to dating or just straight out marrying a do not know who they are once you grow up and your teenage crush growes up they can decide who they are they might be different when you knew them how YOU liked them but that was not then that was who or what they where trying to be sooner or later most teens change and turn into their older more suffisicated selves so in all the teen crush you loved is probably not exactly the person you thought they where it would the same with you, you will change as they will.
