WTF? WHY DOESNT HE EVER...10 POINTS.?

[BONOBO]

OKAY theres this guy who totally acts like he is into me. or at least finds me attractive he tells me i am pretty and alllllll this stuff and i just know he has some feels for me. even if its not much ... but like legit. he was acting like he liked me this wholllleee weeeekkkk man. so i just dont understand. okay I KNOW its JUST FACEBOOK. but i want to know....? WHY! doesnt he ever like my profile pictures. he called me really pretty so i dont understand...he likes all these other girls profile pictures. and stuff. but he will like my cover photo but not my profile picture. and i know he saw mine today because he was online when he saw it. and it was a really pretty one so i dont understand. like forreal? i like his pictures so why doesnt he like mine.... im not popular. not much. but he likes girls photos who are just regular. and i have to say im probably the only girl he finds cute of my race. ( im a different race then him) but i dont think he is racist. so i just dont understand??? i know its not a big deal but it kinda makes me mad. and no he is not trying to make me jealous. its just the fact he really was acting like he liked me...
he does tell me im pretty in front of everyone in my class...... idk i think im not " cool enough" for him...
