He never asks me out to meet and never calls me or texts me...?

i am in a relationship from last 6 months. Initially we used to talk n meet alot but from last 2 months he never asks me out to meet and never calls me or texts me only I am texting him all d time and he never replies on time. When i told him he said theres nothing to worry. He says he love me alot. but his actions are telling a different tale.
