What do i do if i have a boyfriend that asked me out firstbut ignores me alot?

my boyfriend named Connor asked me out last Monday. of course i shyly said "okay". he never texts me back or texts me first ( maybe once every blue moon). and at school he completely ignores me like i don't exist! i'm really afraid hes starting to not like me anymore...but its been an off and on relationship so i'm pretty sure he likes me. what to do?? how do i handle this with out breaking up??
