Long distance in marriage is a disaster?

my husband is thousands of miles away and we talk on the phone every day but its not a good mode of communication. i can't convey my feelings to him. and i've started feeling we're both getting so comfortable staying away from each other that its scary. is our marriage doomed cause of this distance? i miss my husband very much and i love him so much. i can never even imagine leaving or cheating on him or anything but why am i getting comfortable in this set up. i wanted to keep missing him the way i did in the first month. he's gone for 3 months. i think he doesn't miss me as much as he did in the beginning. i'm getting worried. what kind of relationship is this. when he first went away, we both thought we'll die without each other. then daily routine and busy days make the pain gone away. now we just talk and sometimes don't even feel like talking every day. i hate being so far away. to all the wives and husbands, never go faraway from each other.
