Sceptical

Hello guys and gals. Just a week ago a guy I had been hanging out with for a few months told me he liked me. I was sceptical at first but he was a kind guy and he is almost the only one keeping me company as I am lonely in my uni without a group of people to call friends. So I said that I liked him too and now we are in a relationship which I am beginning to regret,as he puts almost no effort into it. I always have to make the first step ,or else we wouldn't even hold hands. I have told him my problems but he doesn't seem to understand. I try to love him but I don't find him attractive anymore. I feel lonely but I don't have the heart to break up with him as it's only the beginning but i honestly don't want to feel so conflicted about my feelings towards him. Just yesterday we were on a date and all I could think about was leaving,which made me feel so terrible. I don't know what to do I thought I could keep being in the relationship until we figure it out but I doubt anything good will come out of that
