What's wrong with him?

There's this guy who always asks to see me, he stays around my block. I was quite busy so I decided to give him just five minute out of my time, besides he is always calling at the last minute. He came immediately,since he stays nearby and told me we should go for a stroll,that he wasn't comfortable with us just standing beside our fence. We walked a little and we sat down beside a neighbor's flat.Well right there he told me he likes me. I made an excuse to leave two minutes later because I felt the setting wasn't appropriate and he doesn't seem to want to make plans for us to properly hangout and he only asks to see me at the last minute,though I know he is single.He calls me to meet up ,but where? He doesn't really say. Due to this I avoid meeting him because am not a child that hangs out beside people's fences. Please what exactly is wrong with him,why doesn't he acknowledge the fact that if he really wants us to hangout ,it should be done in a proper setting ,I.e.park.
