I messed up big time with this guy i like?

Right i went out with this guy before, lets call him Connor, and i was really frigid and scared, i ended up dumping him after about a month, a couple of months later i went back out with him seem as i still liked him, and i didnt even get to meet him before i felt ill (I asked another question and found out it was because i was anxious) and i still really like him. but he got really upset when i dumped him because i told him i didnt like him in that way. and now i'm all confused on what to do, or what to say because i still like him, but when i'm with him i go totally frigid and suddenly i dont like him?:S:S:S:S:S:S Neeeeeeeeeeeeeeeeeed help! x'
