Should I tell him the truth?

The thing is we have been friends for like a month. I asked him if he wanted to hang out (like he said we would. Then he asked who is gonna be there. I said just u and me. He said “Like a date? I’m sorry but I’m talking to someone” and I said “no just hanging out” (I did mean as a date but that was a defense mechanism). Then he said, “oh well I don’t really have a set schedule” I don’t want to lose him as a friend but I also have so many feelings towards him and want to explore that. Now I feel bad that I said no, when I really was just trying to put a wall up.
