Been badly hurt for over a year, now I'm scared of being in a relationship with this new, caring sweet guy?

your thinking to much. its causing you to get confused. just cut the first guy out of your mind then think about if you really like the new guy. do you really want to go out with him? if yes then go for it and it will help you move on. if not then at least its not because of you clinging to the first guy. as far as the first guy goes, if he doesn't like you and isn't good to you you should get over him and try to forget.
