What should I do??!!!!?

If ur not a funny person and she laughs she probably still has feelings for you. If she still wants something to do with yoy and your included in what she does, she wants to be close to you. She doesnt necessarily want to go out with you yet, but i have a feeling that it might happen in the future. She likes you for who you are, regarless if you think your a massive nerd, so dont change too much. Just keep hanging out and give it a little time, things will wOrk out. Wish you the best!
