Why do guys minds change because this guy who i like keeps asking me questions like if we could go anywhere in the world together on a date where would we go and kissing questions?

gurl, guys are like that i had this guy that liked , then he didn't , now he doesn't , i don't now , there like that , my guess is that they see something , there not sure about the situation , they have no clue what to do then they change their mind .... i so its so stupidly confusing ;)
