Was he being pushy about it or no? You say you felt weird about it but did you express that in anyway at the time? This is important because it tells us if he is being a bit manipulative. If nothing like that was going on, it’s probably just a bit awkward between you atm. Also there is no reason you can’t date this guy. This whole ‘don’t date a friend’ mindset is nonsense. A lot of life long relationships start as good friends.
