I'm 18 years old and recently started dating someone I go to college with who is also 18. Eventually I'd like to really get serious with this person but I have no idea how I know if he is ready or even wants to move on to a serious relationship. We haven't been together that long so I don't expect it anytime soon but any advice about how I know when he's ready or how long is to long to just be dating would be great! Thanks.
