What does this mean? is it ok to feel this way?

i have a friend. we barely hang out and we text rarely from time to time. he’s online all the time. but, he never talks to me claiming he’s “antisocial” i don’t know why. i’m really scared to talk to him because he always types “.” after i message him something or “? ” and it makes me feel stupid and insecure and i’m too afraid to tell him. even though he tells me i’m his bff and that he loves me as a friend. he means everything to me but i get mad when we don’t talk bc i feel so lonely.
