Dating soon to be wed man?

Ok, I know is so wrong to be with him, I do understand that. We started as friends...we use to text each other and talk all the time...I'm super attracted tours him...I have try breaking it off with him...and not talking to him...because I DO understand that I'm just that other person for him... but when I do so he'll text me and ask me do U really want thing to end like this? and I said no, I'm just really scared, I don't want to get hurt! I don't want to be your unconditional call, and he said if U were a call I wouldnt do things with U. we have gone away we'll go for dinner and drinks and he also saids he does cares about me and he does has feeling too. I care a lot for him and I do have feelings for him...I have told him I do have feelings for him and he said I want U to have feeling because I feel the same way for U. If someone out there is in the same place as I'm please help me?
