Help become a better gf...?

Ok there is this guy that I asked out. He is my friend. He is so cute, nice and sweet. I asked him out without any reason. Maybe because my friend dare me to do it and maybe because I'm trying to make the guy that I really like jealous. Our first day was great. We hold hands then he said to me... ''I've been rejected so many times'', he said. And I was like ''awww.... like how many times?'' and he goes.. ''like 5 times but it's ok''. So i was like feel very upset and bad for asking him out or for making fun of him just because I want to get the guy that I like jealous. He is nice and I don't want to hurt his feelings AGAIN... then I just realized that I'm starting to love him even it is just the first day. Now, this isn't a joke or set up for me anymore. I think I like him. What should I do to make him feel that I'm not gotta hurt him and how to b a better gf? I am becoming very sweet to him because I am a very sweet person. So... I need help guys!!!!
