Being afraid of being alone

Is it love or am I just lonely? I feel like I am just leading him on. That's not me, I don't do this to people. How can it be love when he is 1000 miles away and he won't call me or video chat with me. I've seen pics but for me I want more. Is that wrong? I feel no connection with him but why can't I tell him and just end it. I worry that I am only with him so I can say I have someone. I've never liked being alone and I was raised to not depend on a man. Is being alone really that scary that I am with someone I'm not attracted to? When it comes down to it I believe that I should just end it. But I'm afraid of hurting his feelings and I've never been one to do so. Should I suck it up and tell him or not? If I wait it will be worse but how to tell him. Now that's the real question.
